Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
9x = 72 ⇒ x = 8
Also
= ( cross- multiply )
6a = 45 ⇒ a = 7.5
And
= ( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
You are trying to get the x by its self so move the -4 to the other side so that you have 5-2x = 8/-4 then subtract 5 from both sides of the equation -2x = (8/-4) - 5 then once again divid so x = ((8/-4) - 5) / -2
Answer:
41
Step-by-step explanation:
3x+4y÷2 for x= 7 and y=10
Substitute the variables with the numbers.
3(7) + 4(10) ÷ 2
3 x 7 = 21
4 x 10 = 40
21 + 40 ÷ 2
Use PEMDAS to complete
40 ÷ 2 = 20
20 + 21 = 41
Answer is 41
