Hours He will work in this Week=20 hours.
Number of Hours he will Teach=x
Number of Hours He will Eat icecream=y
We know
x+y=20
x=20-y (Equation 1)
Teaching French=$12
Eating Icecream=$8
Let He Total Money he Earn from Teaching.
=12×Number of Hours he work
=$12x
Eating Icecream=$8
Total money spent=$8y
But Total Money=$190
MEANS
$12x+$8y=$190
12(20-y)+8y=190
240-12y+8y=190
-4y=190-240
-4y=-50
y=50/4
y=12.5
We know x+y=20
x+12.5=20
x=20-12.5
x=7.5 hours
MEANS He have to teach At least =7.5 hours.To make $190
1.0000!
if this is rigtht please give brainliest, if you need an explication let me know :)
It's D 4 3/8 miles
First you have to multiply 2 1/2 for the mile and 1 3/4 for the inches. You will get 4.375.Convert it to fraction which is 35/8 and simplify it to get 4 3/8.
Hope this helps!

Hi there!
The question here is asking us to multiply two functions together - j(x) and k(x). First, we need to determine the expressions for j(x) and k(x). Since this is given, we can move straight onto multiplying the two functions together, which will give us our answer.
j(x) × k(x)
Substitute expressions -
(x⁴ - 81)(x + 3)
Simplify -
(x⁴ - 81)(x + 3)
x⁵ + 3x⁴ - 81x - 243
Therefore, the answer is x⁵ + 3x⁴ - 81x - 243. Hope this helped!
