Answer:
x= - 9
Step-by-step explanation:
- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9Hey there!
Use the Distributive Property and simplify:
-8(x+7)=16
-8x-56=16
Notice we write -8 right next to x.
Add 56 to both sides:
-8x=16+56
-8x=72
Divide both sides by -8:
x=-9
Hope everything is clear.
Let me know if you have any questions!

2(2w+8)+2w=96 please help with steps
Answer:
w=[tex]\frac{40}{3}[/tex]
Step-by-step explanation:
2(2w+8)+2w=96
Distribute the 2.
4w+16+2w=96
Combine like terms.
6w+16=96
Subtract 16
6w=80
Divide 80 by 6.
w= 13.333333 or [tex]\frac{40}{3}[/tex]

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°
Answer:
x = 84
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the given angles and equate to 360
x + 132 + 54 + 90 = 360
x + 276 = 360 ( subtract 276 from both sides )
x = 84
Answer:
x = 84°
Step-by-step explanation:
→ Recall the fact that angles around a point add up to 360°
360 - (90 + 54 + 132 ) = x
→ Simplify
360 - 276 = x
→ Simplify again
84 = x ∴ x = 84°

at a basketball game, 18% were supporting the visiting team. if 2624 people attending supported the home team, what was the total number of people attending the game?
Answer:
2624= 82%
18%= 2624/82=32. 32*18=576
Step-by-step explanation:
If 2624 people attending supported the home team, the total number
of people attending the game will be 3200.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that 18% were supporting the visiting team and 2624 people attending supported the home team as a result 82 % were supporting the home team,
Let the total number of people attending the game be x.
⇒82% of x = 2624
⇒(82/100)×x= 2624
⇒x= (2624×100)÷82
⇒x=3200
Hence, if 2624 people attending supported the home team, the total number of people attending the game will be 3200.

Ed has 30 sweets. The ratio of red sweets to yellow sweets is 2:3 How
many red sweets does Ed have?
Answer:
The ratio of red sweets to yellow sweets is 12.
Step-by-step explanation:
let the number of red sweet = 2x
number of yellow sweet = 3x
according to question:
red sweets + yellow sweets = total sweet
2x +3x = 30
5x = 30
x = 30/5 = 6
red sweet = 2x = 2× 6 = 12
yellow sweet = 3x = 3× 6 = 18

Two more than 11 times a number is equal to 24. What is the number?
Answer:
2
Step-by-step explanation:
Brainliest?!?!?!?
The answer to this would be 2.
Step by Step Explanation
Equation: 11x+2=24
Variable for the missing number: x
To do this, I suggest writing out an equation with the variable X to represent the missing number that we are trying to find. The equation would look something like this: 11x+2=24.
From here, to solve the equation, subtract 2 from both sides, which would then get the equation to be 11x=22. From here, you would then divide both sides by 11 to get the variable on it's own, which would be x=2. Since x is the variable that we are using to represent the missing number, the missing number would be 2.

Answer:
1.) Triangle ABC is congruent to triangle DCB
Step-by-step explanation:
For the first one, the first 3 steps proved that all 3 sides in the 2 triangles formed by the diagonal are congruent to each other, meaning triangle ABC is congruent to triangle DCB (I named it like that specifically because the way you name the triangles has to be the exact same way you named the other triangle).
For the second one, the congruency statement should be GL ≅ AD, because the HL congruence theorem states that if a hypotenuse and leg of one right triangle is congruent to the hypotenuse and leg of another right triangle, those triangles are congruent.
Answer:
choice 4) Triangle ABC is congruent to triangle DCB because of the Side-Side-Side theorem
Step-by-step explanation:
How do you find the x intercept and y intercept on a graph and when given an equation?
Answer:
In a graph, the x-intercept will be the point in which the line crosses the horizontal line of the plane.
The y-intercept is found when the line crosses the vertical line of the plane.
In an equation, y = mx + b, the y-intercept is the value of b, and the x-intercept is shown when y = 0. (substitute y for 0 and find the value of x)
