Answer: 26
Step-by-step explanation:
You first add all of the numbers together. Put 34 twice though because the question said 34 Tuesday AND Wednesday. Then you divide the total/sum by the number of numbers. Luckily since the question is going by days of the week you divide by 7. That should give you your answer.
Easier answer: add 25, 34, 34, 23, 18, 22, and 26. Then divide by 7. Answer will be 26. :)
-8x - 2y = -4
When y = -5x
-8x - 2(-5x) = -4
- 8x + 10x = -4
2x = -4
x = -4/2 = -2
Tell whether the product of Prxs and Q5x3 is defined. If so, give the dimensions of PQ.
undefined
defined; 7 x3
defined; 3 x 7
defined; 5 x 5
For the top shape, x = 11, y = 10 and z = 14.
Start with the equation: 11y + 7y = 180 because those two angles are supplementary. Solving that will give you that y = 10.
The angle that is labelled 7y is therefore 70 degrees. We can write the following equation will the 5x because it is corresponding to the 70 degree angle.
5z = 70
z = 14
And we can also write and solve for the x, using the 70 degree angle.
70 + 10x = 180
10x = 110
x = 11
