Answer:
6 and 5
Step-by-step explanation:
6 * 2 = 12
12 - 5 = 7
6 and 5 is your answer
Answer: 6; 5
Step-by-step explanation:
Based on the questions, we set up two equations, let the x be the first number, and y be the second number.
x + y = 11
2x - y= 7
x = 11 - y [Subtract y from both side]
2x - y = 7
2(11 - y) - y = 7 [Plug in 11-y for x, solve for y]
22 - 2y - y = 7
22 - 3y = 7
-3y = -15 [Subtract 22 from both side]
y = 5
x + y = 11 [Plug in 5 for y, solve for x]
x + 5 = 11 [Subtract 5 from both side]
x = 6

What should be added to both sides of the equation below to complete the square?
x?
+ 6x = -8
O-4
O-2
O-9
09
Answer:
Step-by-step explanation:
x² + 6x = 8
Coefficient of the x term: 6
Divide it in half: 3
Square it: 3²
Add 3² to both sides of the equation to complete the square and keep the equation balanced:
x² + 6x + 3² = 8 + 3²
(x+3)² = 17

Find the value of x. Round to the nearest tenth.
Use this to find the value of x: tan (x) = 4/3
Using tan(x) = 4/3
X = arctan(4/3)
X = 53.1 degrees
Answer:
Step-by-step explanation:
tan x = 4/3
tan x=1.333333
divide both sides by tan
x=1.33333/tan
x=tan inverse of 1.33333
x=53.130
x=53.13 to the nearest tenth

The base area of a square-based prism is 25 ft squared. One of the lateral faces of the prism is 30 ft squared. What is the surface area of the prism?
Step-by-step explanation:
Given data
lateral surface area= 30ft
base area of squared prism = 25 ft means height= 25
(therefore, square object length breadth and height same )
total surface area = lateral surface * height
= 30ft*25ft
=750 ft square.

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?
Answer:
42
Step-by-step explanation:
the ratio 2:4 can be reduced to 1:2,
where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.
If there are 14 girls, then there must be 28 boys (14 x 2 = 28).
Now to get the total number we need to add the total number of boys and girls together.
So 14 + 28 = 42
Hope it helps :)
Answer:
32
Step-by-step explanation:
14 + 28 = 32
2 x 7 = 14
4 x 7 = 28

0 > 3x - 3 - 6
what is answer
Answer:
x < 3
(*￣3￣)╭
Answer:
The answer is x < 3.
Step-by-step explanation:
1) Simplify 3x - 3 - 6 to 3x - 9.
[tex]0 > 3x - 9[/tex]
2) Add 9 to both sides.
[tex]9 > 3x[/tex]
3) Divide both sides by 3.
[tex] \frac{9}{3} > x[/tex]
4) Simplify 9/3 to 3.
[tex]3 > x[/tex]
5) Switch sides .
[tex]x < 3[/tex]
Therefor, the answer is x < 3.

x=
Answer:
x = 6
Step-by-step explanation:
∠ AFB and ∠ EFC are vertically opposite angles and are congruent , then
21x - 9 = 117 ( add 9 to both sides )
21x = 126 ( divide both sides by 21 )
x = 6
The measured valued of x is 6.
What are Vertical Angle?Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines.
We have,
<AFB = 21x- 9
and, <DFC = 27
Using Vertical Angle
<AFB = (<EFD + <DFC)
21x - 9= (90 + 27)
21x - 9 = 117
21x = 117 + 9
21x = 126
x = 6
