Josiah works at an electronics store as a salesperson. Josiah earns a 2% commission on the total dollar amount of all phone sale

salantis [7]

Answer: the equations are

0.02x + 0.07y = 156

y = 300 + x

Step-by-step explanation:

Let x represent the total dollar amount of phone sales that she makes.

Let y represent the the total dollar amount of computer sales that she makes.

Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that

0.02x + 0.07y = 156 - - - - - - - - - - -1

Josiah had $300 more in computer sales than in phone sales. This means that

y = 300 + x

Two quadrilaterals are similar. The length of the row longest sides of the first quadrilateral are 40in and 60in. The lengths of

Andreyy89

Answer:

The sides of the first quadrilateral are 60 in, 40 in, 30 in and 12,5 in

The sides of the second quadrilateral are 24 in, 16 in, 12 in and 5 in

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

Arrange the sides of each quadrilateral from largest to smallest

<u><em>First quadrilateral </em></u> <u><em>Second quadrilateral</em></u>

Longest side=60 in Longest side=c in

Second side=40 in Second side=16 in

Third side= a in Third side= 12 in

Fourth side=b in Fourth side=5 in

so

$\frac{60}{c}=\frac{40}{16}=\frac{a}{12}=\frac{b}{5}$

<em>Find the value of c</em>

$\frac{60}{c}=\frac{40}{16}$

$c=60(16)/40$

$c=24\ in$

<em>Find the value of a</em>

$\frac{40}{16}=\frac{a}{12}$

$a=40(12)/16$

$a=30\ in$

<em>Find the value of b</em>

$\frac{40}{16}=\frac{b}{5}$

$b=40(5)/16$

$b=12.5\ in$

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.

Margarita [4]

If you would like to simplify Q + S - T, you can do this using the following steps:<span>

Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8

</span>Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3

The correct result would be <span>8m + 7n - 3.</span>

14=2y/5 and explain how you got it??

son4ous [18]

2y/5 is the same thing as 2/5 times y so

14=2/5(y) then you divide both sides by y and you get

14/y=2/5 then from there multiply both sides by 1/14 to get

y=0.03

What would z and x equal i need help plz

KATRIN_1 [288]

Answer:

Angle Z =79° and x = 31.33

Step-by-step explanation:

From the shown parallel and intersecting lines , it is found that,

∠z° = 79° interior angle on same side of transversal

and ∠z = (6x - 109°) corresponding angles

i.e 79°+109°= 6x

or, 188 = 6x

i,e x = 31.33

Hence angle z =79° , and x = 31.33
