Final answer:
To solve the equation 2q + 10 = 7q, subtract 2q from both sides and then divide by 5, resulting in q = 2.
Explanation:
To solve the equation 2q + 10 = 7q, you need to isolate the variable q on one side. Here are the steps you should follow:
Subtract 2q from both sides to get all q terms on one side of the equation: 2q + 10 - 2q = 7q - 2q, which simplifies to 10 = 5q.
Divide both sides by 5 to solve for q: 10 / 5 = 5q / 5, resulting in q = 2.
Therefore, the value of q that solves the equation is 2.

-3 times what equals 9
The value to fill in the blank is -3.
So, -3 x -3 = 9.
We have,
To solve the equation -3 x __ = 9, we need to find the value to fill in the blank that makes the equation true.
Let's denote the value we need to find as "x".
When we multiply -3 by "x", it means we are adding -3 to itself "x" times.
So, the equation becomes -3 times "x" equals 9:
-3x = 9.
To solve for "x", we can divide both sides of the equation by -3:
-3x / -3 = 9 / -3
This simplifies to:
x = -3
Therefore,
The value to fill in the blank is -3. So, -3 x -3 = 9.

A triangle has the following angle measures: 125°, 15°, and 40°. Which of the following statements best describes its drawing?
A)It is impossible to construct a triangle with these angle measures.
B)There is one possible triangle with these angle measures.
c)There are many possible triangles with these angle measures.
D)There are many possible similar triangles with these angle measures.
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Measures of angles are as follows:
125°, 15°, 40°
As we know the sum of all angles in a triangle is supplementary i.e. 180°.
∠A+∠B+∠C=180°
125°+15°+40°=180°
Therefore, it is satisfying the angle sum property.
So, it can form a triangle.
Now, we will check for uniqueness.
As similar triangles need two angles to be equal by AA criteria , their sides can vary with two equal angles.
Hence, there is possibility to have many possible similar triangles with angle measures.
Therefore, Option 'D' is correct.

Which number line represents all of the values of x for the equation x2 = 64?
Answer:
We are asked to find all the values of x on the number line that satisfies the given quadratic equation:
[tex]x^2=64[/tex]
We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.
on taking the square root on both the side of the equation we obtain:
[tex]x=\pm 8[/tex]
Hence we get two points on the number line.
x=8 and x= -8.
These are the discrete values we did not get any interval of the solution.

Paige has to make invitation cards for a party. If she can make 18 cards in 2 days, how many cards can she make in 30 days?
Answer:
270 cards
Step-by-step explanation:
18 cards in 2 days means 9 cards in a day. So that means that we have to multiply 9 cards a day by the number of days, which is 30.
9 x 30 = 270
Meaning, Paige made 270 cards in 30 days.
A store sells T-shirts for $14 and sweatshirts for $25. They sell 200 items and earn $3,515 in sales. Which equation could be used to find the number of T-shirts (t) sold? Answer Options with 4 options A. 14t + 25(200 − t) = 3515 B. 14 + 25(200 − t) = 3515 C. 14t + 25(200 + t) = 3515 D. 14 + 25(200 + t) = 3515

An angle measures 102° less than the measure of a supplementary angle. what is the measure of each angle?
The measure of two angles are 141° and 39°.
What are supplementary angles?When the sum of two angles equals to 180°, then those angles are said to be supplements of each other and hence called supplementary angles.
Given that, An angle measures 102° less than the measure of a supplementary angle.
Let the angles be x and y, then according to question,
x+y = 180°
x-y = 102°
Solving the equation by elimination method, we get,
2x = 282°
x = 141°
Put x = 141°
141°-y = 141°
y = 39°
Hence, the asked angles are 141° and 39°

To find the measures of the angles, set up an equation using the property that supplementary angles add to 180 degrees. Solving the equation yields one angle measuring 39 degrees and the supplementary angle measuring 141 degrees.
When dealing with angles and their measurements, it's important to remember fundamental properties, such as the fact that the sum of supplementary angles is 180 degrees. Given that an angle is 102° less than its supplementary angle, we can set up an equation to find the measure of each angle. Let's call the first angle x; therefore, the supplementary angle will be x + 102°.
Using the property that the sum of supplementary angles is 180°, we can write the equation:
x + (x + 102°) = 180°
2x + 102° = 180°
2x = 180° - 102°
2x = 78°
x = 39°
Thus, the measure of the first angle is 39° and that of the supplementary angle is 39° + 102° = 141°.
