2(7a + 4)
14(a + 1)
Answers
The solution is Option C.
The value of the equation A = 14a + 8 can be simplified to A = 2 ( 7a + 4 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 14a + 8 be equation (1)
Now , the equation (1) can be simplified as
Taking the common term as 2 in the equation , we get
A = 2 ( 7a + 4 )
The 2 is taken as common term , and the multiples are the values 7a and 4
So ,
The value of A = 2 ( 7a + 4 )
A = 2 ( 7a ) + 2 ( 4 )
The value of A = 14a + 8
Therefore , the value of A is 2 ( 7a + 4 )
Hence ,
The value of the equation A = 14a + 8 can be simplified to A = 2 ( 7a + 4 )

help .. Solve the literal equation cy−7=5d+3y for y .
Answers
The literal equation cy - 7 = 5d + 3y can be solved for y by first bringing all the y terms to one side, and then factoring y out and dividing by the remaining coefficient to isolate y. The solution is y = (5d + 7) / (c - 3).
To solve the literal equation cy - 7 = 5d + 3y for y, we need to isolate y on one side of the equation. First, we want to bring all the terms containing y to one side and the rest to the other side. We achieve this by subtracting 3y from both sides of the equation and adding 7 to both sides, leading to cy - 3y = 5d + 7.
Now, we factor y out of the terms on the left side thus: y(c - 3) = 5d + 7. Finally, we divide both sides by (c - 3) to get y by itself: y = (5d + 7) / (c - 3). Therefore, we have isolated y and expressed it in terms of c and d.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
Answers
To find the equation of a line parallel to 3y - x = -12 that goes through the point (18, 2), first find the slope of the given line, which is 1/3. Then, use the point-slope form with the given point and the slope to write the equation of the desired line, which is y = (1/3)x - 4.
Explanation:To write an equation of the line that passes through the point (18, 2) and is parallel to the line 3y - x = -12, we first need to find the slope of the given line. For a line to be parallel, it must have the same slope as the line to which it is parallel. We start by putting the equation of the given line in slope-intercept form (y = mx + b).
First, isolate y:
3y = x - 12
y = (1/3)x - 4
The slope (m) of the given line is 1/3. Our parallel line should have the same slope, so we'll use this slope and the point (18, 2) in the point-slope form of a line equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.
Now, plug in the values:
y - 2 = (1/3)(x - 18)
This is the point-slope form of the equation for our parallel line. To put it into slope-intercept form, we distribute and simplify:
y - 2 = (1/3)x - 6
y = (1/3)x - 4

If the consumer price index changes from 125 in september to 150 in october, what is the rate of inflation?
a. 20.0%
b. 16.7%
c. 9.1%
d. 45.5%
Answers
Rate of Inflation = [New price - Base price]/Base Price * 100
Rate of inflation = (150 - 125)/125 * 100 = 20%
So, the answer is A.
If the consumer price index changes from 125 in september to 150 in october, the rate of inflation is a. 20.0%
Further explanationInflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When inflation is too high, it is not good for the economy or individuals. Inflation always reduce the value of money, unless interest rates are higher than inflation. The less chance there is that savers will see the real return on their money if the inflation gets higher. There are causes of inflation such as demand-pull and Cost-push. They are responsible for a general rise in prices in an economy.
Policies to reduce inflation are such as monetary policy (Higher interest rates), Tight fiscal policy (Higher income tax and/or lower government spending that will reduce aggregate demand and leading to lower growth and less demand pull inflation).
The rate of inflation = 20%.
September's price = 125
October's price = 150
Rate of inflation = [tex]\frac{(150-125)}{125} * 100[/tex]
[tex]\frac{25}{125 } *100[/tex]
[tex]=0.2 * 100 \\= 20%[/tex]

The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm. What is the approximate difference between m∠C and m∠A?
Answers
make sure your calculator is in Degree mode, if you need the angles in degrees, or Radian mode if you need them in radians.
and their difference is clearly just C - A.
Answer
Difference between m∠C and m∠A= 44.76
Step-by-step explanation:
The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm.
Hypotenuse AC = 13 cm
So angle B is right angle = 90 degrees
AC is the hypotenuse
BC is the adjacent side for C
cos (c)= adjacent side / hypotenuse
C= cos^-1(BC/AC)
[tex]C= cos^{-1}(\frac{5}{13})= 67.38[/tex]
angle B is a right angle= 90 degree
Angle C= 67.38 degrees
Sum of angles in a triangle is 180°
A + B +C = 180
A + 90 + 67.38 = 180
A= 180 - 90 - 67.38=22.62
Difference between m∠C and m∠A= 67.38 - 22.62=44.76
A number changed to 12.6 after it was rounded. To what place waa the number rounded? Explain how you know
Answers
if it was 12.67 rounded, then it would have been rounded to the nearest hundredths place because ur last digit is in the hundredths place
and if it was 12.678 rounded, then it would have been rounded to the nearest thousandths place because ur last number is in the thousandths place
u get it ?
Answer:
The number round to nearest tenths.
Step-by-step explanation:
Given : A number changed to 12.6 after it was rounded.
To find : To what place was the number rounded?
Solution :
The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.
In number 12.6 it was rounded to the nearest tenths.
Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.
So, the number can be 12.56, 12.57, 12.58, 12.59
If they all round we get the number 12.6.
