Answer:
-13/5 or -2.6
Step-by-step explanation:
Step 1: Flip the equation.
−5x−2=11
Step 2: Add 2 to both sides.
−5x−2+2=11+2
−5x=13
Step 3: Divide both sides by -5.
-5x 13
----- = -----
-5 -5
x = -13/5

Joan has $5.40 worth of change in nickels and dimes. If she has 4 times as many nickels as dimes, how many of each type of coin does she have?
Answer:
18 dimes and 72 nickels
Step-by-step explanation:
If Joan has 4 nickels per dime, that means that she will have change in groups of 30 cents (4*5=20+10=30). If we divide 5.40 by 0.30, we get 18. We now know there are 18 groups of 30 cents. One dime per group of 30 cents means that there are 18 dimes, and 4 nickels per group of 30 cents means that she has 72 (4*18) nickels.
Now to check our math:
[tex]72n+18d=5.40\\72(0.05)+18(0.10)=5.40\\3.60+1.80=5.40\\5.40=5.40[/tex]
Our math adds up, which means that we got the right answer :)

Which statements are true for the following expression? 30 · (8 + 7 + 3) Check all that are true. The solution is the product of two factors. The second factor is itself the sum of three terms. The solution is the sum of two terms. The coefficient is 3. The second factor is the sum of two terms.
Answer:
True:
The solution is the product of two factors.
The second factor is itself the sum of three terms.
False:
The solution is the sum of two terms.
The coefficient is 3. (This one I'm confused about. There is no x/letter term, so there shouldn't be a coefficient in this problem at all.)

Please help need to get too 80%
Answer:
the scale factor is 5:36.
Step-by-step explanation:
To solve the question, we note that 1 yard = 3 feet and 1 feet = 12 inches
Where the scale of the drawing is 5 inches = 1 yard,
we have the scale of the drawing is 5 inches = 36 inches
5 inches is equivalent to 36 inches in real life
That is the scale is 5 is to 36 which is 5:36.

There are four students working on a project in math class. Miguel has completed 1/8 of the project, Gina has completed 13% of the project, Jatziry has completed 0. 10 of the project, and Kwa has completed 1/9 of the project. Make a list of the students in order from least to greatest by the amount of the project they have completed.
There are a few methods to doing this, but lets make every number a fraction. (You could make them all percentages or decimals if you want, but it is more difficult in my opinion.)
Miguel: 1/8
Gina: 13/100
Jatziry: 10/100 = 1/10
Kwa: 1/9
Now we need to find the least common denominator, which is 1800.
Now you have these fractions:
Miguel: 225/1800
Gina: 234/1800
Jatziry: 180/1800
Kwa: 200/1800
Now you can easily list these in order
180/1800 < 200/1800 < 234/1800 < 225/1800
Jatziry < Kwa < Gina < Miguel
Sorry if I made any mistakes, I realized Jatziry was a part of the problem halfway through.
Mark cast a shadow that is 4 feet long. At the same time, a nearby tree casts a shadow that is 20 feet long. If mark is 6 feet tall, how tall is the tree?
Answer:
30 ft
Step-by-step explanation:
We can use the given information to set up a ratio...
[tex]\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}[/tex]
[tex]\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}[/tex]
We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):
120 = 4x
Divide both sides by 4
x=30 ft
Write the point slope form of the equation of the line through the given point and slope:
PLEASE EXPLAIN. (STEP BY STEP)
Step-by-step explanation:
the general point-slope form is
y - y1 = m(x - x1)
with (x1, y1) being a point on the line, and m being the slope.
so,
y - -1 = 4/3 × (x - 3)
or simplified
y + 1 = 4/3 × (x - 3)

Can someone please help
Answer:
10.) If you buy all larger cans (aka the 7-gallon cans), you would have saved approx. $30.21
9.) Seth would need a score of 95% in order to average an 80%
Step-by-step explanation:
10.) It costs $15.50 per 5-gal. If you want to buy 45 gallons, it would cost you $139.50 if you bought 5-gallon cans.
It costs $17.00 per 7-gallon. If you want to buy 45 gallons, it would cost you $109.29 if you bought 7-gallon cans.
Now, let's compare prices. Buying 45 gallons worth of 7-gallon cans is less expensive by.... (139.50 - 109.29 = 30.21)
Therefore, you saved $30.21.
9.) An average is done by adding up all the numbers and dividing it by how many numbers you added it by. Let's write an equation to make things easier. So far, we don't know the score he needs to get on his fourth test so let's make it a variable x.
(82 + 68 + 75 + x) / 4 = 80
Let's solve for x.
(82 + 68 + 75 + x) / 4 = 80 *Multiply both sides by 4
82 + 68 + 75 + x = 320 *Add like terms
225 + x = 320 *Subtract 225 from boths to get x on one side
x = 95
