The three steps are shown below were used to find an expression equivalent to 2/5( 15x- 30y)+10x

Tresset [83]

step 1 is to distribute the bracket by $\frac{2}{5}$

= $\frac{2}{5}$ × 15x - $\frac{2}{5}$ × 30y + 10x

= 6x - 12y + 10x ← step 1

a metalworker has meal alloy that is 15% copper and another alloy that is 60% copper. how many kilograms of each alloy should th

iragen [17]

Let L be the low copper alloy and H be the high copper alloy.
We need 0.15L + 0.60H = 0.42 and L + H = 100

L=100 - H
Substituting this into the second equation for L, we get:
0.15(100-H) + 0.60H = 0.42(H+L)
15 - 0.15H + 0.60H = 0.42(H+100-H)
15 + 0.45H = 0.42(100)
0.45H = 42 - 15 = 27
H = 27/.45 = 60 lbs

Back substitution, L = 40 lbs.

a cell phone company offers two different monthly plans.plan a charges $41 for unlimited cell phone minutes plus $0.10 per text

fgiga [73]

41+0.10x = 31+0.15x

10 +0.10x=0.15x

10=0.05x

x=10/.05

x= 200 text messages

check 200*0.10 = 20 +41 =61

200*0.15 = 30+31 = 61

they equal each other so number of texts is 200
