Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5
A bakery has 36 glazed donuts on display. This is 80% of the total number of donuts. What is the total number of donuts in the bakery?
Answer:
it is 64.8, but you have to round to the nearest number, so i would say 65 :)
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
% means out of 100, so 80% is 80/100
Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =
36 times 1.25 = 45
There's 45 donuts
Double check:
45(80/100) = 36, we're right

write the equation of the line thay passes through the point (2,-1) and has a slope of -3
Answer:
Y = -3x -1
Step-by-step explanation:
Y = mx + b
Y is the y intercept (x,y) always graph on y axis
M is the slope
Answer:
Step-by-step explanation:
use the point slope equation.
y-y1 = m(x-x1)
the point is (x1, y1) = (2, -1)
the slope is m = -3
y+1 = -3( x-2)
y = -3x +6-1
y = -3x +5
Using the order of operations, what should be done first to evaluate 6 + 10-(-5)(3) - 5?
Answer:

What can you conclude from the diagram
Answer:
You can conclude from the diagram that m∠P is less than m∠N ⇒ A
Step-by-step explanation:
In any triangle, you can arrange the lengths of the sides according to the measure of the opposite anglesIn any triangle, you can arrange the measure of the angles according to the lengths of the opposite sidesExample:
In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B
Let us use this fact to solve the question
→ In ΔKNP
∵ KP = 8 units
∵ KN = 6 units
∵ 6 < 8
∴ KN < KP
∵ ∠P is opposite to the side KN
∵ ∠N is opposite to the side KP
∵ KN < KP
→ By using the fact above
∴ m∠P < m∠N
∴ m∠P is less than m∠N
∴ You can conclude from the diagram that m∠P is less than m∠N

A home improvement store buys snow shovels from a supplier for $8.50. The day before a snowstorm the store manager marks up the price by 180% to calculate the retail or selling price. What is the retail price of the snow shovel?
Answer:
The retail price is $15.30
Step-by-step explanation:
To solve this, turn the percentage into a decimal. Do this by dividing it by 100.
180 ÷ 100 = 1.8
Then, multiply the supplier price by the decimal
8.5 × 1.8 = $15.30

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost
Answer:
the cost is now $5.40
Step-by-step explanation:
if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.
we multiply if we are trying to find the new amount and we divide to find the old amount.
Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.
