Answer:
The length is 73m
Step-by-step explanation:
51x2=102
248-102=146
146÷2=73
10 is twice the size of 5 thus 100% bigger
B=blue
g=green
r=red
2 times as many blue as green
b=2g
3 times as many red as blue
r=3b
subsitute 2g for b
r=3(2g)=6g
r=6g
r+g+b=765
so we subsitute
r=6g
g=g
b=2g
6g+g+2g=765
add like terms
9g=765
divide both sides by 9
g=85
subsitute
b=2b
b=2(85)
b=170
170 blue
This is the rule for any calculation of this type. Note that you can replace X(B) by X(A) and the same for Y because the answers are squared and you'll always get the same value
Answer:
distributive property of multiplication over addition
Step-by-step explanation:
The distributive property of multiplication over addition:
a(b + c) = ab + ac
You have
-4(x + 4) = -4x - 16
which is an application of that property.
