Answer:
c. Change the length of side CB to 8 feet
Step-by-step explanation:
If the figures are similar, the ratios should be the same
Take the side of the larger triangle over the same side of the smaller
PR PQ RQ
----------- = --------------------= ----------------
AC AB CB
7.5 5 10
----------- = --------------------= ----------------
6 4 9
7.5 /6 = 1.25
5/4 = 1.25
10/9 =1.1111(repeating)
The bases are not in the right ratio. RQ over CB = 1.25. Since RQ = 10 and the ratio is 1.25, we can solve for CB
10/CB = 1.25
Multiply by CB on each side
10 = 1.25CB
Divide by 1.25 on each side
10/1.25 = CB
8 =CB
It is the Top left answer!
Answer:
well to make it easier i will make 3/4 equilvilent to 1/12
so 4 * 3= 12 so then that means i times 3*3=9
so 3/4=9/12
and if each bag is 1/12 pounds then Jackson can fill 9 whole bags with trail mix
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Whatever you multiply or divide to the numerator, you do to he denominator.
Here, 12 was divided by 4 to obtain 3 in the other fraction. So, the missing number has to be 16 divided by 4, which gives 4
Answer:
Step-by-step explanation:
1) 2x -y = 1 -------1
3x - y = -6 ------2
Subtract eqn 2 from eqn 1
-x = 1--6 = 7
x = -7
Put x= -7 in eqn 1
2*-7-y = 1
-14-y = 1
- y = 15
y = -15
2) 4x +2y = 10------1
y = 4x + 2--------2
Put eqn 2 in eqn 1
4x + 2 ( 4x+ 2) = 10
4x + 8x + 4 = 10
12x = 6
x = 6/12 = 1/2
Put x = 1/2 in eqn 2
y = 4* 1/2 + 2= 2 + 2
= 4
3) 6x - y = 2------1
y = 3x + 4---------2
Put eqn 2 in eqn 1
6x - (3x +4) = 2
6x - 3x - 4 = 2
3x = 6
x = 2
y = 3*2 + 4 = 6 + 4
= 10
