To find the x-intercept ;

Just need to put 0((zero)) instead of y in the equation.

Let's do it....

3x - 7y = 21

3x - 7(0) = 21

3x - 0 = 21

3x = 21

Divided sides by 3

3 / 3 × x = 21 / 3

x = 7

Thus the x-intercept is 7 .

To find the y-intercept ;

Let's do it....

3x - 7y = 21

3(0) - 7y = 21

0 - 7y = 21

-7y = 21

Divided sides by -7

-7 / -7 × y = 21 / -7

y = - 3

Thus the y-intercept is -3.

Your answer is 1.65.

(may have a hard time explaining it)

SO, there are 8 hotdogs and 4 bags of chips, 4 times 1.25 is 5, and 18.20 minus 5 is 13.20, so the chips are out of the equation. Now all we must do is divide what's left (13.20) by 8:

13.20/8=1.65

Answer:

I got 11/14

Step-by-step explanation:

I found a common demoninator of 14 I multplied 2/7 by two to get 4/14 then added the two fractions together

4/14+7/14 would equal 11/14

Answer:

grab ur calculator for these. when dividing, they will end up in decimal format. for it to be a precentage, take that number and multiply by 100 to get a percent.

To convert back to fractions, divide the number by 100

eg 7%

7/100

that's the fraction. (decimals is just the full dividing)

Answer:

B

Step-by-step explanation:

oranges weigh 0.5 and grapefruits weigh 1.5

The required: 13 oranges and 15 grapefruits would weigh 29 pounds.

The correct option is A.

One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.

Let's use a system of equations to solve this problem:

Let's call the weight of an orange "x" and the weight of a grapefruit "y". Then we can write:

10x + 20y = 35 (equation 1)

16x + 10y = 23 (equation 2)

We want to find the weight of 13 oranges and 15 grapefruits, which we can represent as:

13x + 15y

In this case, we can multiply equation 1 by -8 and equation 2 by 15:

-80x - 160y = -280 (equation 1, multiplied by -8)

240x + 150y = 345 (equation 2, multiplied by 15)

Now we can add the two equations to eliminate y:

160x = 65

Solving for x, we get:

x = 65/160

Now we can substitute this value of x back into one of the original equations to solve for y. Let's use equation 1:

10(65/160) + 20y = 35

Simplifying this equation, we get:

13/32 + 2y/4 = 7/2

Multiplying both sides by 32, we get:

13 + 16y = 112

Solving for y, we get:

y = 99/16

Finally, we can substitute these values of x and y into the expression for 13 oranges and 15 grapefruits:

13x + 15y = 13(65/160) + 15(99/16) = 29.0625

Therefore, 13 oranges and 15 grapefruits would weigh approximately 29.0625 pounds, which is closest to answer B, 29 pounds.

Answer:

1.6

Step-by-step explanation:

The amount of snow fell each hour is 1.6 inches per hour.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity

Given that,

Time Amelia and her brother played in the snow = 3 hours

Amount of snow fell at that time = 4.8 inches

That is 4.8 inches of snow per 3 hours

We have to calculate the unit rate of the amount of snow falling in an hour.

Amount of snow in 1 hour = 4.8 / 3 = 1.6 inches per hour

Hence the 1.6 inches of snow is falling per hour.

"George earns $9.50 per hour and $35.00 commission per sale, but he pays $12.00 in license fees each week. Mary earns $13.50 per hour and $11.25 for every defect she corrects, but she must pay $37.00 for tool rentals each week. The expressions below represent their individual earnings for every two-week pay period. George: 9.5h+35s−2(12) Mary: 13.5h+11.25d−2(37) where: h = the number of hours worked s = the number of sales George makes d = the number of defects Mary corrects if George and mary work the same hour each period, which expression represents their combined earning for one day earning period"

given

week pay period.

George: 9.5h+35s−2(12)

Mary: 13.5h+11.25d−2(37)

their combined earning is the sum of the individual earning

Answer:

55

Step-by-step explanation:

I believe it's 55 because the triangle has to equal 180

so I subtracted 70 from 180 and x can't be 70 because they don't have the same lengths

subtracting  70 from 180 gave me 110 then I divided by 2 since both the top angle and x would have the same angle in degrees xD

the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c

Given

K = 0.03W/m°C

Required

Convert K to W/cm°C

Since 1m = 100cm,

K = 0.03w/1×100cm°C

K = 3×10^-2w/10² cm°C

K = 3 × 10^-2w/10² cm°C

K = 3w× 10^{-2-2}cm°C

K = 3w×10^-4cm°C

K = 0.0003w/cm°C

Answer:

0.0003

Step-by-step explanation:

DID IT ON KHAN

and Since 1m = 100cm,

K = 0.03w/1×100cm°C

K = 3×10^-2w/10² cm°C

K = 3 × 10^-2w/10² cm°C

K = 3w× 10^{-2-2}cm°C

K = 3w×10^-4cm°C

K = 0.0003w/cm°C
