Answer:
141 5/7
Step-by-step explanation:
8c + 10b ÷ 7a
Let c = 7, b = 12, and a = 5
8*7 + 10*12 ÷ 7*5
Multiply and divide from left to right
56+120 ÷7*5
56+ 600/7
Get a common denominator
392/7 + 600/7
992/7
Change from an improper fraction to a mixed number
141 5/7
Answer:
I think its 2
Step-by-step explanation:
The two shapes look exactly the same except the first one is smaller.
Which means that the side where x is will be the same as the where 8 is on the first diagram.
So 2 +6 is 8.
Which is why u think it has to be 8
Hope this helps!
Answer:
x = 9.6
Step-by-step explanation:
The figure is a similar figure and the quadrilaterals (4 sides) created are related to each other by the same ratio.
So we can say:
8 goes with x as (8+12) goes with 24
We can setup a ratio and solve for x:
So x = 9.6
Answer:
x = 10.296
y = 5.831
Step-by-step explanation:
You can use the Pythagorean theorem to solve the triangles shown in various ways.
9²+5²=x²
x = 10.296
5²+3²=y²
y = 5.831
