Answer:
Peter's company uses on:
Monday = 4 gallons
Tuesday = 4 gallons
Wednesday = 4 gallons
Thursday = 8 gallons
Step-by-step explanation:
If they made a total of 20 gallons over the course of these four days, how many gallons did they make each day? Monday
Let the gallons of paint used be Peter's company on Monday, Tuesday, and Wednesday since it is the same amount be represented by x
On Thursday, they made twice as many as any of the previous days.
= 2x
Hence:
x + x + x + 2x = 20 gallons
5x = 20 gallons
x = 20 gallons/5
x = 4 gallons
Note that:
Thursday = 2x
Hence, = 2 × 4 gallons = 8 gallons
Hence, Peter's company uses on:
Monday = 4 gallons
Tuesday = 4 gallons
Wednesday = 4 gallons
Thursday = 8 gallons
Answer:
x = 10
y = 4
Step-by-step explanation:
5x-4y=24 ------>( 1 )
-2x+7y=12 ------>( 2 )
( 1 ) × 2
(2) × 5
10x - 8y - 10x + 35y = 48 + 60
<u>27y</u><u> </u>= <u>108</u><u> </u>
27 27
y= 4
5x - 4× 4 = 24
5x - 16 = 24
x = 10
99
Explaining
X= 93 +6
X= 99
The designers will Charge the same amount at $700. 500+100*2=700 and 600+50*2=700
Midpoint means that the line segments beside the midpoint are same legnth
therefor QP=PR in legnth
therefor
2x-6=x+7
solve
remember thath you can do antyhingn to an equaiton as long as you do it to both sides
2x-6=x+7
minus x from both sides
2x-x-6=x-x+7
x-6=0+7
add 6 to both sides
x+6-6=7+6
x=13
qr=pr
pr=x+7
x+7=13+7=20
answer is 20 units
