Answer:

85-86%

Step-by-step explanation:

Make it an equation

You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X

36/42 = X/100

36 X

42 100

Cross multiply

Do math and solve for X

36 x 100 = 42 x X

3600=42X

X=85.71

the area of a rectangular flower bed is 6.5sq.feet. the width of the flower bed is 0.75 feet. what is the length of the flower?

RSB [31]

width= w

length = l=w+5

Area = l * w

104 =(w+5) * w

w2 +5w -104 =0

(w+13)(w-8)=0

w=13 and w=8

so width =8

length=13

Answer:

See step-by-step explanation

Step-by-step explanation:

Question 3: (4, -3)

Solving through elimination: Multiply the first equation by -3.

-3x+6y=-30

3x-5y = 27

Add. The x drops out.

y= -3

Substitute -3 in for y.

x-2y=10

x-2(-3)=10

x+6=10

x=4

Question 4: (2,5)

Solve through elimination: Multiply the second equation with 3.

$\frac{3}{2} x+y=8$

$\frac{9}{4} x-y=-\frac{1}{2}$

3/2= 6/4

15/4x=7.5

x=2

3/2 (2) + y = 8

3+ y =8

y=5

Question 5: (6,4)

Use your graph to graph.

$y=-\frac{1}{3} x+6$

Slope of -1/3

Y-intercept of 6 (0,6)

X-intercept of 18 (18,0)

$y=\frac{3}{2} x-5$

Slope of 3/2

Y-intercept of -5 (0,-5)

X-intercept of $\frac{10}{3}$ (

Question 6: (5, -7)

$Ax+2By=-41$

$4Ax-By=88$

$3A+2B(4)=-41$

$4A(3)-B(4)=88$

Solve by substitution:
