Can u help me too
Answer:
34 degrees
Step-by-step explanation:
Well, since all of the interior angles equal 360 degrees, the following equation can form:
[tex](3x-6)+2x+108+88=360[/tex]
Simplifying, this becomes:
[tex]5x-6+196=360[/tex]
[tex]5x+190=360[/tex]
[tex]5x=170[/tex]
[tex]x=34[/tex]
To check my work, I will substitute this value back into the equation:
[tex](3(34)-6) +2(34)+108+88=360?[/tex]
[tex](102-6)+68+108+88=360?[/tex]
[tex]96+68+108+88=360?[/tex]
[tex]360=360[/tex] ✔

Answer:
x = 2, y = 5
Step-by-step explanation:
Given the 2 equations
y = - 2x + 9 → (1)
y = 4x - 3 → (2)
Substitute y = 4x - 3 into (1)
4x - 3 = - 2x + 9 ( add 2x to both sides )
6x - 3 = 9 ( add 3 to both sides )
6x = 12 ( divide both sides by 6 )x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4(2) - 3 = 8 - 3 = 5
Then x = 2, y = 5
Which equation models the statement shown? y varies directly with x and =25 y = 25 when =5 x = 5 .
Answers
Answer:
The value of y is 125 when x=25.
Step-by-step explanation:
It is given that y varies directly as x. It means y is proportional to x.
Where k is constant of proportionality.
It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.
Divide both sides by 5.
The value of k is 5.
The relation between x and y is defined by the equation
Put x=25 in the above equation.
Therefore the value of y is 125 when x=25.

A user car dealer brought a car for $12,000 and wants to sell it at a 15% profit. How much should he sell the car for?
Answers
Answer:
$13,800
Step-by-step explanation:
She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800
Which phrase can be represented by an equation? twice as much as a number 12 less than a number half of a number is 15 the difference of 20 and a number
Answers
Answer:
Half of a number is 15
Step-by-step explanation:
First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.
An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.
Twice as much as a number: 2X
12 less than a number: X - 12
Half of a number is 15: X/2 = 15
The difference of 20 and a number: 20 - X
As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

Remember
1 gallon contains 64ounces
1 cup contains 8ounces
1 pint contains 16ounces
We know that 2 gallons (128oz total) are needed to fill the bucket.
First, Omar pours 64 ounces into the bucket so we have 128 - 64 = 64 ounces left to fill.
Second, Penny pours 8 cups which is the same as 64 ounces (8cups x 8 ounces = 64 ounces total) into the bucket.
Stop here and add up the water in the bucket.
The bucket has only 128 ounces capacity total which means Omar and Penny have filled up the bucket with 64 ounces each. 64 x 2 = 128 ounces
The bucket is full, Ronnie actually makes it overflow. So Sierra will pour 0 quarts of water into the bucket.
Answer:
= 2.75823202 quarts
Step-by-step explanation:
1.40513707 imperial quart = 64 US ounces
1.66534763 imperial quart = 8 cups
0.83267382 imperial quart = 2 US pints
1.40513707+1.66534763+ 0.83267382 = 3.90315852
conversion to gallons = 1.171875
2 - 1.171875 =0.828125
0.828125 gallons conversion x 3.33 = 2.75823202 quarts
2.75823202/0.828125 shows s the conversion rate from gallons to quarts
= 3.33
The answer is = 2.75823202 quarts

Damon buys lumber worth $562. He gets a 20% contractor's discount. The sales tax is 6%. His credit card gives him 2% off. How much does he pay?
Answers
Answer: $404.64 and 157.36 dollars to save
Step-by-step explanation:
Answer: $467.05
Step-by-step explanation:
The price is $562
20% off = 562 - 20% of 562 = 562 - 0.2(562) = $449.60
6% tax = 6% = 6/100 = 0.06
449.60 + 0.06*449.60 = $476.58
2% off from credit card = 476.58 - 0.02(476.58) = $467.05

nick works at a job that pays $6.00 per hour. if he works h hours and makes 192.00 dollars this week, how many hours did nick work this week?
Answers
C. h=32
6*32=192
Answer:Ok so he makes about 6.00 bucks an hour so if he works 30 hours how much will he need to make 192.00 bucks.
Step-by-step explanation: Multiply 6.00 by 30 hours= 180 and u need 192$
so 192-180=12 so add 2 more hours to your 30 hours which makes it 32 hours.
If nick works 30 hours plus 2 more hours a week, he will make a total of $192.
