Cross product are both equal to 21.

Step-by-step explanation:

5 peanut butter biscuits for $3

7 beef treats for $4.20

So, proportional equation is

[tex]\frac{5}{3}[/tex] = [tex]\frac{7}{4.20}[/tex]

Cross multiply

Answer:

Step-by-step explanation:

You would use PEMDAS (or GEMDAS) to solve it.

First solve the parenthesis:

[tex]6*4^{2} +(6-8)*3[/tex]

[tex]6*4^{2} -2*3[/tex]

Then you would solve the exponent:

[tex]6*4^{2} -2*3[/tex]

[tex]6*16 -2*3[/tex]

Then you would solve for multiplication/division in the order they appears:

[tex]6*16 -2*3[/tex]

[tex]96 -2*3[/tex]

[tex]96 -6[/tex]

Finally, subtract/add the numbers in the order they appear:

[tex]96 -6[/tex]

[tex]90[/tex]

can someone help me find the area please?

Answers

Answer:

100 in ^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+ b2) *h  where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 16+9) * 8

   = 1/2 ( 25) *8

   = 100 in ^2

1/2*(l+L)*h
1/2*(9+16)*8=100

3. You sell storm windows and doors. You receive a straight

commission of 8% of the selling price of each storm window

and 12% of the selling price of each door. What total

commission will you receive for selling $5,400 in storm

windows and $28,790 in doors?

Answers

Answer:

[tex]\$3886.8[/tex]

Step-by-step explanation:

Commission received on selling each storm window [tex]=8\%[/tex] of the selling price of each storm window

Commission received on selling each door [tex]=12\%[/tex] of the selling price of each door

Amount earned on selling storm windows = $5,400

Amount earned on selling doors = $28,790

Commission received on selling storm windows [tex]=\frac{8}{100}(5,400)=\$432[/tex]

Commission received on selling doors [tex]=\frac{12}{100}(28,790)=\$3454.8[/tex]

Therefore,

Total  commission received [tex]=432+3454.8=\$3886.8[/tex]

5x-2y ≤ 20 can you guys solve this.

Answers


Your answer is y ≥ −10 + 5x/2

Answer:

Step-by-step explanation:

Let's solve for x.

5x−2y≤20

Step 1: Add 2y to both sides.

5x−2y+2y≤20+2y

5x≤2y+20

Step 2: Divide both sides by 5.

5x /5 ≤ 2y+20 /5

x≤ 2 /5 y+4

Answer:

x≤ 2 /5 y+4

Let's solve for y.

5x−2y≤20

Step 1: Add -5x to both sides.

5x−2y+−5x≤20+−5x

−2y≤−5x+20

Step 2: Divide both sides by -2.

−2y /−2 ≤ −5x+20

−2 y≥ 5 /2 x−10

Answer:

y≥ 5 /2 x−10
