Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

x = 1 and y = 4

Step-by-step explanation:

Multiply the top equation by 7 on both sides, and then cancel it out:

7(5x + y) = 7(9)

35x + 7y = 63

Now use this equation to cancel out -7y on the second equation:

35x + 7y = 63

10x - 7y = -18

45x = 45

x = 1

Now that we have our x-value, we can plug it into one of our two original equations:

5(1) + y = 9

y = 4

Answer:

A) 6.54cm

Step-by-step explanation:

a^2 + b^2 = c^2

5.7^2 + 3.2^2 = c^2

Answer:

So for box 5 you would say that the weight of the box (48)  plus the movers weight (185)  is less than or equal to the amount of weight the elevator can hold which represents the 2,000. The last box could be something like "Amanda is shipping a 48lb T.V. the sound bar it came with and speakers totals to 180lbs. Amanda can't ship these items if they exceed 2,000 pounds total. Create an inequality to show if Amanda will be able to ship all these items without going over the allowed weight.

Answer:96.34%

Solution for 79 is what percent of 82:

79: 82*100 =

(79*100): 82 =

7900: 82 = 96.34%

Answer:

64.72

79 percent *82 =

(79:100)*82 =

(79*82):100 =

Now we have: 79 percent of 82 = 64.78

Answer:

Micheal will spent 40 $ on each of his friends

Step-by-step explanation:

160$÷4=40$

why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.

Answer:

x≤40. He can spend about $40 on each friend

Step-by-step explanation:

I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.

Answer:

x = 49

Step-by-step explanation:

Everything is proportional because the sun is basically in the same spot.

We can make the equation:

[tex]\frac{56}{16}=\frac{x}{14}[/tex]

Using cross multiplication,

16 * x = 56 * 14

16x = 784

Divide both sides by 16 to isolate x,

x = 49
