what is negative 7 minus negative 2
Answer:
-5
Step-by-step explanation:
-7 - (-2)
-7 + 2
Example: If you owe someone $7, and you give them $2, how much do you still owe? You are owing him $7 so it's a negative and you give him $2 which is a negative as well since you are giving it to him. So, to answer how much do you still owe, you would add $2 to the $7 you owed, so now, you owe him $5, which is a negative since you OWE him.
Hope this helps:)
can you guys help with these questions??
Answer:
Step-by-step explanation:
<3 = 55° ( vertically opposite angles )
<4 = 180 - 105 = 75° ( linear pair )
<5 = 180 - ( 55 + 75 ) ( angle sum property of a triangle )
= 180 - 130
= 50°
<1 = <2 ( angles opposite to equal sides )
let < 1 and < 2 be x
55 + 2x = 180 ( angle sum property of a triangle )
2x = 180 - 55
2x = 125
x = 125 / 2
x = 62.5
therefore, < 1 = <2 = 62.5°

A pair of shoes costs $30.99 and the state sales tax is 4%. Use the formula C = p + rp to
find the total cost of the shoes, where C is the total cost, pis the price, and r is the sales tax
rate.
$32.23
$39.19
$43.39
$34.99
Answer:
the answer is A. $32.23
Step-by-step explanation:
Answer:
$32.00
Step-by-step explanation:
To find the sales tax always multiply the sales tax to to the cost of you item.
Being your sales tax is 4% you will Multiply 30.99 x .04 (not just 4)
30.99 x .04 = 1.2396 ( round to the nearest tenth) since the number after the 3 is 5 or above ,,,,round it off to 24...Making it $1.24 (tax) Now add that to your cost of the shoes
$30.99 + $1.24 = $32,23
For future : if the tax is 10, 20, 35%... You will multiply the cost of item by .10, .20, .35 (put the point in front of it .

Use the substitution method to solve the system of equations. Choose th correct ordered pair. y = 8x - 4 x = 4 A. (2. 12) OB. (4, 28) C. (4, 4) D. (2.4)
9514 1404 393
Answer:
B. (4, 28)
Step-by-step explanation:
Substitute the value of x into the first equation. This gives you the value of y.
y = 8x -4x = 4After substitution, we have ...
y = 8(4) -4
y = 28
Then the point is (x, y) = (4, 28).

Mr. Myers wants to join a music club. The 1st choice music club charges a $5 sign-up fee and $1 each song.The superstar music club charges no sign-up fee and charges $3.50 each song. After how many song will the cost of the music clubs be equal?
1st choice music club equation: _____ Superstar Music Club Equation: _____
Solution: _____
THIS WAS DUE YESTERDAY, with a lot of other confusing problems! Please help!
Answer:
The answer is 2 songs and the solution is 7.
Step-by-step explanation:
1. Make an equation for each club. The 1st choice music club equation is 5+1x and the Music Club equation is 3.50x.
2. Go down the number line starting with 1 and replace x with that number and solve the equation until you get the same number on each side with the same replacement number.
3. So, 5+1x becomes 5+1(2) and that would equal 7. Then do 3.50x becomes 3.50(2) and that would also equals 7.
Note: When a number has a number next to it in parentheses then that means to have to multiply first. If you don't then you will get the wrong answer.

Answer:
n=7.5°
Step-by-step explanation:
As the two lines are parallel do the equation is
(10n+19)+(12n-4)=180
10n+19+12n-4=180
22n+15=180
22n=180-15
22n=165
n=165/22
n=15/2
n=7.5
n=7.5°

4. Tres albañiles trabajaron en una construcción. Francisco trabajó el doble de horas que Eduardo y Eduardo trabajó el cuádruple de horas de las que trabajó Hugo. Entre los tres hermanos trabajaron 104 horas ¿Cuántas horas trabajó cada uno? Planteamiento algebraico: Procedimiento:
Answer:
La cantidad de horas que trabajó Hugo son 8, mientras que Eduardo trabajó 32 horas y Francisco 64 horas.
Step-by-step explanation:
En primer lugar, para determinar la ecuación que debes resolver, es conveniente establecer la variable a la que debes encontrar una solución en la ecuación. Entonces, llamas x a la cantidad de horas que trabajó Hugo.
Luego, sabes que Eduardo trabajó el cuádruple de horas de las que trabajó Hugo, esto es, cuatro veces más de las horas trabajadas por Hugo. Esto se expresa matemáticamente como 4*x.
Finalmente, Francisco trabajó el doble de horas que Eduardo, que se calcula multiplicando a las horas trabajadas por Eduardo por 2: 2*4*x= 8*x
Entre los tres hermanos trabajaron 104 horas. Esto indica que la suma de las horas trabajadas por Francisco, Eduardo y Hugo debe ser 104 horas. Esto se expresa matemáticamente como:
x + 4*x+ 8*x= 104 (Planteamiento algebraico)
Resolviendo (Procedimiento):
13*x=104
[tex]x=\frac{104}{13}[/tex]
x=8
Esto significa que la cantidad de horas que trabajó Hugo son 8.
Eduardo trabajó 4*x, esto es 4*8, que da como resultado 32 horas. Entonces Eduardo trabajó 32 horas.
Por último, Francisco trabajó 8*x. Siendo x=8, entonces 8*8=64. Entonces Francisco trabajó 64 horas.
Hugo trabajó 8 horas, Eduardo trabajó 32 horas y Francisco trabajó 64 horas.
Dado que tres albañiles trabajaron en una construcción, y Francisco trabajó el doble de horas que Eduardo y Eduardo trabajó el cuádruple de horas de las que trabajó Hugo, y entre los tres hermanos trabajaron 104 horas, para determinar cuántas horas trabajó cada uno se debe realizar el siguiente cálculo:
E + F + H = 104F = 2EE = 4HF = 8HH + 4H + 8H = 10413H = 104H = 104 / 13H = 8Así, Hugo trabajó 8 horas, Eduardo trabajó 32 horas y Francisco trabajó 64 horas.

Andrea bought tacos from a food truck and left 25% tip of $2.00. What was the price of Andreas tacos, before tip?
Answer:
$8
Step-by-step explanation:
25% is .25, also known as 1/4. So if you think of it that way, $2 is 1/4 of the entire payment that was added to it. 2*4 is 8, so the price of the tacos was $8 before any tip was added. Andrea paid $10 in total if you include the tip.
