#8) Subtract 350 from each side then divide each side by 25 to get (c-350)/25 = h.
Plug in 950 for c to get (950-350)/25 = h.
600/25 = h = 24 hours.
#9 is the same as number 8 just with one more variable. Subtract 2.25h from both sides and divide both sides by 1.75. Then plug in 18.25 for t and 5 for h. Then solve for d.
Answer: add
Step-by-step explanation:
1➡Problem ▶4x - y = 6
Steps▶4(x)-y- 6=?
y-intercept▶6÷-1 = -6, right ?
x-intercept ▶ 6÷4 which is also equal. to▶ 3÷2 , they both equal 1.5 , right?
The answer⬇
Your slope▶4
y-intercept ▶ -6
x-intercept ▶1.5
2➡Problem 3x + 2y = 8
Steps▶3(x)+2(y)-8=?
y-intercept▶ 8 ÷ 2 = 4, right?
x-intercept 8 ÷ 3 = 2.67 ,right?
Slope▶-3.0÷2.0 = -1.50
Your answer⬇
y-intercept ▶4
x-intercept ▶2.67
Slope ▶1.50
3 ➡Problem y - 1/2x = 3/4
Steps ▶ 3÷4 = .75
1÷2 = .5
y-intercept ▶ 3÷4 = .75,right?
x-intercept ▶3 ÷ (-2) = -1.50; 1.5 , right ?
Slope ▶ 1 ÷ 2 = .5, right ?
your answer⬇
y-intercept : .75
x-intercept: 1.5
Slope .5
We have to calculate the area of a rectangular quilt.
area of a rectangle=length x width
Data:
length=60 in=60 in(1 foot/12 in)=5 ft
width=40 in=40 in(1 foot/12 in)=3.33 ft
Area of the rectangula quilt=(5 in)(3.33 in)=16.67 ft²
Now, we have to calculate the cost of this quilt
$1.50-----------------1 ft²
x------------------------ 16.67 ft²
x=($1.5 * 16.67 ft²)/1 ft²=$25
Answer: the cost of the rectangular quilt was $25
