I’m pretty sure it 9 13/20
The answer is 1
Use the discramnt formula
Where a is 81, B is 18, and c is 1
We get
We then get 324-324=0
Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.
Answer:
1:20
Step-by-step explanation:
x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours
Answer:
$12,000
Step-by-step explanation:
Kabore wants to make $700 this week. We can subtract 100 from that amount because his base pay is $100.
700 - 100 = 600
This leaves us with 600. Kabore has to make $600 from his sales. However, he only gets paid 5% of his sales. So, 600 is worth 5% of his sales. This can be represented in an equation, where x represents his sales and 0.05 is 5% in decimal form:
= 0.05
Multiply both sides of the equation by x to isolate it on one side:
600 = 0.05x
Divide both sides by 0.05 to find the value of x:
12000 = x
Kabore needs to sell $12,000 worth of product if he wants to make $700 this week.
Hope this helps :)
