1 answer:

6 0

1 Solve for yy in -2x+y=1.3−2x+y=1.3How?
y=1.3+2xy=1.3+2x
2 Substitute y=1.3+2xy=1.3+2x into 2(0.5x-y)=4.62(0.5x−y)=4.6How?
2(-1.5x-1.3)=4.62(−1.5x−1.3)=4.6
3 Solve for xx in 2(-1.5x-1.3)=4.62(−1.5x−1.3)=4.6How?
x=-2.4x=−2.4
4 Substitute x=-2.4x=−2.4 into y=1.3+2xy=1.3+2xHow?
y=-3.5y=−3.5
5 Therefore,
x=-2.4x=−2.4
y=-3.5y=−3.5

Davis has 141 figures in his action figure collection. One-third of the figures are sports related. How many of the figures in D

Lelu [443]

We have been given that Davis has 141 figures in his action figure collection. One-third of the figures are sports related.

To find the number of figures that are not sports related we will find 2/3 of 141 as 2/3 of the figures will be not related to sports.

$\text{ Figures not related to sports}=141\times\frac{2}{3}$

$\text{ Figures not related to sports}=47\times2$

$\text{ Figures not related to sports}=94$

Therefore, 94 figures in Davis’ collection are not sports related.
