Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
<u>x + y = 195</u>
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120
Okay. So we have our like terms, which are the constants. Those are 2, 3, and 6. 2 * 3 is six. 6 * 4 is 24. Then x, y, and z go together, because there's not anything to combine with. So (2x)(3y)(4z) equals 24xyz.
Answer:
<em><u>y= -3x+3</u></em>
Step-by-step explanation:
<span>Find the equation of the line that passes through the points (3,-2) and (4,5).</span>
5-(-2)=7/ 4-3=1
So the slope is 7. Now plugin 7 for "m" and use one of the two points for x and y
5=7(4)*b
5=28*b
5-28=b
-23=b
So y=7x-23
