Answer:
140
Step-by-step explanation:
Let the number be represented by x. You are given ...
(3/5)x = 42
Multiplying by 10/3 gives ...
(10/3)(3/5)x = (10/3)(42)
2x = 140 . . . . the value of twice the number
Answer:
Step-by-step explanation:
A=1/2(r+2)
2A=f(r+2)
2A/f=r+2
2A/f-2=r
Answer:
x=38
Step-by-step explanation:
Answer:
Blake will jog 12 blocks
Step-by-step explanation:
Allison : Blake = 3 : 2
If they keep jogging at the same rate, how many blocks will Blake jog if Allison jogs 18 blocks?
Allison : Blake = 18 : x
Equate the ratios
3 : 2 = 18 : x
3/2 = 18/x
Cross multiply
3 * x = 2 * 18
3x = 36
Divide both sides by 3
x = 36 / 3
= 12
x = 12
Blake will jog 12 blocks
we can use synthetic division
and then we can find quotient
we can see in the image
we will get



so, we get
