Answer:

x=10

Let's solve your equation step-by-step:

4x+40=80

Step 1: Subtract 40 from both sides

4x+40−40=80−40

4x=40

Step 2: Divide both sides by 4

4x/4=40/4

Answer:

x=10

Answer:

collect like terms

4x=80 - 40

4x= 40

divide both sides by 4

4x/4÷ 40/4

x = 10

Answer:

6 runners finished the race

Step-by-step explanation:

Total number of runners = 54

In the first half of the race, 1/3 of them dropped out

= 1/3 of 54

= 1/3 * 54

= 54/3

= 18 runners

Runners remaining after first half = total runners - dropped out runners at first half

= 54 - 18

= 36 runners

In the second half of the race, 5/6 of the remaining runners dropped out

= 5/6 * 36

= (5*36)/6

= 180/6

= 30 runners

Runners remaining after second half = runners remaining after first half - dropped out runners at second half

=36 - 30

= 6 runners

Therefore, 6 runners finished the race

Answer:Find the GCD (or HCF) of numerator and denominator

GCD of 56 and 100 is 4

Divide both the numerator and denominator by the GCD

56 ÷ 4

100 ÷ 4

Reduced fraction:

14

25

Therefore, 56/100 simplified to lowest terms is 14/25

Answer:

a reflection over the line y= -x

Answer:

x=7

Step-by-step explanation:

5x-6=3x+8

subtract 3x from both sides

2x-6=8

add 6 to both sides

2x=14

divide both sides by 2

x=7

Answer:

The answer is D

Step-by-step explanation:

because if you do the methoes method you know that it rules out 1 and 2 and 3 after you do that its just between C and D, for the caunususicon it has to be D, that is why i think its D. hope this helps

Answer:

A

Step-by-step explanation:

Answer: A = -2/3

Step-by-step explanation:

To find the slope use the slope formula

y2 - y1  over

x2 - x 1

I suggest learning the slope formula if you'll keep getting h.w like this.

to find the slope

I'll use any 2 points

10 - 8 = 2

7 - 10 = -3

The slope is -2/3

Answer:

[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]

Step-by-step explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :

[tex]A=\text{side}^2[/tex]

So,

[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]

So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].

Answer:

C. 1 1/2

Step-by-step explanation:

Answer:

14m squared

Step-by-step explanation:

2.5×2=5

5÷2=2.5

2.5 is the area for each triangle and there are four triangles altogether so

2.5×4=10

to find the square do 2×2=4

so 4m+10m=14m

Answer:

18 trucks of delivery

Step-by-step explanation:

Total pallets of concrete blocks ordered = 252 pallets

If each truck can carry 14pallets, then;

1 truck = 14pallets

To determine the number of delivery truck 252pallets can carry, we can express this as:

x truck = 252pallets

Divide both expressions

1/x = 14/252

Cross multiply

14x = 1×252

14x = 252

x = 252/14

x = 18

Hence the manger should expect 1 18 trucks of delivery

Given:

Consider the complete question is "A field provides grazing for 18 sheep for 8 days. How many days grazing would it provide for 24 sheep?".

To find:

The number of days the field provides grazing for 24 sheep.

Solution:

We have,

If number of sheep = 18, then, number of days = 8.

If number of sheep = 24, then, number of days = x.

Now, the products of number of sheep and number of days are equal because they represent the total work done.

[tex]18\times 8=24\times x[/tex]

[tex]\dfrac{18\times 8}{24}=x[/tex]

[tex]\dfrac{144}{24}=x[/tex]

[tex]6=x[/tex]

Therefore, the field provides grazing for 24 sheep for 6 days.

Answer: Blll's family has 70% of driving left.

Step-by-step explanation:

The total mileage of the trip = 3,000 miles.

miles driven so far = 900miles

Miles of diatance left = 3000- 900=2100

Percentage of driving left =  Miles of diatance left / Total miles to cover x 100

=2100/3000 x 100

= 7/10  x100

70%
