Answer:

$13.60

Step-by-step explanation:

First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):

$1.25*10=$12.50

Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:

0.55*2=$1.10

Then we add these two together to get:

$12.50+$1.10=$13.60

Pls help me with the inverse operation of this problem. Best answer gets brainliest
timurjin [86]

Answer:

x=7

Step-by-step explanation:

I believe we are solving for x. In that case, let us start by moving 1 to the other side.

\frac{4(x+3)}{5} = 8

Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:

4(x+3)=40

Now, we may divide both sides by 4 to get rid of the coefficiant:

x+3=10

When we subtract both sides by 3, we get

x=7

<em>I hope this helps! :)</em>

Please Help!!

Answer:

D:) (2,2,) is the Answer

Step-by-step explanation:

Solve the following system:


{X - 2 Y = -2 | (equation 1)


{3 X - 2 Y = 2 | (equation 2)



Swap equation 1 with equation 2:


{3 X - 2 Y = 2 | (equation 1)


{X - 2 Y = -2 | (equation 2)



Subtract 1/3 × (equation 1) from equation 2:


{3 X - 2 Y = 2 | (equation 1)


{0 X - (4 Y)/3 = (-8)/3 | (equation 2)



Multiply equation 2 by -3/4:


{3 X - 2 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Add 2 × (equation 2) to equation 1:


{3 X+0 Y = 6 | (equation 1)


{0 X+Y = 2 | (equation 2)



Divide equation 1 by 3:


{X+0 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Collect results:


Answer:  {X = 2 , Y = 2

A box contains 4 black shirts, 8 blue shirts, 4 black pants, and 10 blue pants. Determine the probability of randomly selecting
Rashid [163]
<h3>Answer:  11/13</h3>

============================================================

Explanation:

Add up the four numbers given: 4+8+4+10 = 26 items total

Kick out the 4 black shirts since they are neither blue, nor are they pants.

So we have 26-4 = 22 items that are blue or a pair of pants (or both).

Divide that over the total (26) to get the probability we're after:

22/26 = (11*2)/(13*2) = 11/13

Side note: 11/13 = 0.8462 = 84.62% approximately

FIND om if LO bisects
disa [49]
First you use Pythagorean theorem to find LO is square root of 194(13^2 + 5^2)=13.9. Then use the same method to find OM (194+13^2=363, square root of 363 is 19.1) and get that OM is 19.1

If you solve a linear equation you have two different lines.

Now with that being said the solutions are as follows;

<u>One Solution</u>: The slopes are different

<u>No solution</u>: The slopes are the same and the y intercepts are different

<u>Infinite Solutions</u>: The slopes are the same and the y intercepts are different
