2x-y=10 y=-4x+2 substitution method
Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).

A store has shirts on display. Seven of the shirts are red. There are 5 more blue shirts than green shirts. There are 2 fewer yellow shirts than green shirts. If there are 28 shirts in all, how many shirts are there of each color? Ask for details Follow Report
Answer:
7 red shirts
6 green shirts
11 blue shirts
4 yellow shirts
Step-by-step explanation:
Let y represent the number of green shirts.
So y+5 is the number of blue shirts.
And y-2 is the number of yellow shirts.
And we have 5 red shirts.
Therefore,
7+5+y+y-2+y=28
12-2+3y=28
10+3y=28
3y=28-10
3y=18,divde through by 3
y=6

In triangle RST, the measure of angle T=90°, the measure of angle R=82°, and TR=44 feet. Find the length of ST to the nearest tenth of a foot.
Answer:
[tex]x=6.183ft[/tex]
Step-by-step explanation:
From the question we are told that:
Angel of side [tex]T=90[/tex]
Angel of side [tex]R=82[/tex]
Length Side [tex]TR=44[/tex]
Generally the equation for Angle of side ST [tex]\theta[/tex] is mathematically given by
Since Angle in Triangle =180 therefore
[tex]\theta=180-(90+82)[/tex]
[tex]\theta=8[/tex]
Therefore Applying sine rule to get Length of ST x
[tex]\frac{x}{sin\theta}=\frac{TR}{sin82}[/tex]
[tex]x=\frac{44}{sin82}*sin8[/tex]
[tex]x=6.183ft[/tex]
