Answer:

the second one for #4 and the third one for #5

Step-by-step explanation:

4. The sum of x and y is 24, so x+y = 24. The difference is 15, so x-y = 15, or

y-x=15 (they didn't specify which was which). Therefore, A, C, and D are correct, so x = 15-y is the answer (x = 15-y is the same as x+y = 15, which is false).

Matt = 6 apple pies + 4 lemon pies and he got 80 dollars.

Ming = 6 apple pies + 5 lemon pies and he got 94 dollars.

If apple pie is "a" and lemon is "l":

6a + 4l = 80

6a + 5l = 94,

so C is the answer

FP!!!!!!!!!!!!!!!!!!! if ur up ( 10 x 8 ) + 150

taurus [48]

Answer:

220

Step-by-step explanation:

first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80

first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80then we have to open bracket 80 +150

first we have by Bracket of BODMAS rule then we have to multiply 10 *8 = 80then we have to open bracket 80 +150 = 220

(10*8) +15

Solution

Solution= (80) +150

Solution= (80) +150= 80+150

Solution= (80) +150= 80+150=. 220

Solution= (80) +150= 80+150=. 220

What is the solution to this system of linear equations2x+3y=3 and 7x-3y24

Kay [80]

For this case we have a system of two equations with two unknowns:

$2x + 3y = 3\\7x-3y = 24$

We follow the steps below:

We add the equations:

$9x = 27$

We divide between 9 on both sides of the equation:

$x = \frac {27} {9}\\x = 3$

We substitute the value of "x" in the first equation and find the value of y:

$2 (3) + 3y = 3\\6 + 3y = 3\\3y = 3-6\\3y = -3\\y = \frac {-3} {3}\\y = -1$

Thus, the solution of the system is: (3, -1)

Answer:

(3, -1)

-5^2 + (-15) ÷ (-3) + 20 Solve using PEMDAS showing work

oee [108]

In PEMDAS, there is no parentheses in this equation, so we move on to exponents.

-5^2 is 25
Now, we divide -15/-3 then we get 5
Next, we do -3+20=17
25+5+17 would be 47

Your answer should be 47!
Hope this helps (:
