Answer:
140 = 40 + 10x
Step-by-step explanation:
The watch is 140 in total. He can pay 40 dollars currently. 10x is the amount of payments there are. How much he can pay with each payment (10x) is unknown so that is why there is the variable.
Answer: -9/16
Step-by-step explanation:
10y+12=-6y+3
16y=-9
Y=-9/16
The formula for this is
. If the diameter is 8 the radius is 4, so filling in accordingly we have
and
which is
and when you multiply in 3.14 you get that A = 401.92 or B above.
Lets represent a tin of beans as 
and a jar of jam as 
.
Therefore
3b+4j=2080 and 5b=2000.
Now we can say that b=400.
Substitute b in 3b+4j=2080 for 400.
3*400+4j=2080
Simplify
1200+4j=2080
4j=880
j=220.
Therefore
1 tin of beans is 400 grams and 1 jar of jam is 220 grams.
First, you need to create a unit rate.
The car travels 182 miles on 14 gallons of gas.
To create a unit rate, you would have to divide 14 by 182.
182 mi 13 mi
———— = ———-
14 gal 1 gal
Then, you would need to multiply the numerator and denominator by 8 because the question is asking how far the car can travel on 8 gallons of gas.
13 mi x 8 104 mi
——— = ————
1 gal x 8 8 gal
So, your answer is the car travels 104 miles on 8 gallons of gas.
