Answer:
-20 = - 20
Step-by-step explanation:
Suppose the number is x
three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.
So we can write
x - 3 = 2x +14 - - - - - A
subtract x from both sides
x - x - 3 = 2x - x +14
-3 = x +14
Subtract 14 from both sides
-3 - 14 = x +14 - 14
-17 = x
Or x = - 17
Now can verify our answer by putting the value of x in Eq A
-17 - 3 = 2 x (-17) +14
-20 = - 34 +14
-20 = - 20
I hope this helps. :)

X=23
Step-by-step explanation:
x + (-12) = 11
Open the bracket
x-12=11
Collect like terms
X=11+12
X=23
4. Asia is designing a triangular-shaped window with a height of 15 inches and
an area of 135 square inches. What is the length of the base of the window?
Answer:
18in
Step-by-step explanation:
Given data
Height h= 15 in
Area= 135 in^2
The expression for the area is given as
Area= 1/2 Base * Height
substitute
135= 1/2* Base*15
135= 7.5 Base
Base= 135/7.5
Base= 18 in
Hence the base is 18in

which is equivalent to the expression (2x+4)(x-6)?
Answer:
2(x² – 4x – 12)
Step-by-step explanation:
(2x+4)(x–6) →
2(x+2)(x–6) →
2(x(x–6) + 2(x–6)) →
2(x² – 6x + 2x – 12) →

[tex] \sqrt{652 \times 652} [/tex]
Answer:
652
Step-by-step explanation:
[tex]\sqrt{652 \times 652}[/tex] is equal to [tex]\sqrt{652^{2} }[/tex], and the square root of a number squared is always the original number, so [tex]\sqrt{652^{2} }[/tex] is equal to [tex]652[/tex].

Work out the area of the trapezium ABDE.
A
В.
7.5 cm
2.5 cm
С
5 cm
E
Answer:
Area = 50 cm²
Step-by-step explanation:
Area of a trapezium ABDE = ½(a + b)h
where,
a = BD = 2.5 cm
b = AE = 7.5 cm
h = DE = ?
We need to find DE ti be able to calculate the area.
DE = CE - CD
DE = CE - 5
Since ∆ACE is similar to ∆BCD, therefore:
AE/BD = CE/CD
Plug in the values
7.5/2.5 = CE/5
Cross multiply
CE*2.5 = 7.5*5
CE*2.5 = 37.5
Divide both side any 2.5
CE = 37.5/2.5
CE = 15
Thus, DE = CE - 5 = 15 - 5
DE = 10
✅Area of trapezium = ½(BD + AE)DE
= ½(2.5 + 7.5)*10
= ½(10)10
= 50 cm²
What is the area of the trapezoid?
9 yd
8 yd
13 yd
Answer:
area = 88 yd²
Step-by-step explanation:
area = 1/2(b1 + b2)h = 1/2(9 + 13)(8) = 88 yd²
Answer:
88 yd^2.
Step-by-step explanation:
Area of a trapezoid = 1/2 * h * (a + b) where h = height, a and b are lengths of 2 parallel side.
Area = 1/2 * 8(9+13)
= 4 * 22
= 88 yd^2.
Which dilation is shown by the graph?
Answer:
D. D₂ (∆XYZ)
Step-by-step explanation:
Dₙ = (x,y) → ((n)x, (n)y)
_________________
X = (-1, 2).
Y = (2, -1).
Z = (-2, -1).
_________
Dₙ ∆XYZ:
X(-1, 2) → X'(-2, 4)
Y(2, -1) → Y'(4, -2)
Z(-2, -1) → Z'(-4, -2)
______________
-2 / -1 = 2, 4 / 2 = 2.
4 / 2 = 2, -2 / -1 = 2.
-4 / -2 = 2, -2 / -1 = 2.
_______________
D₂ = (x,y) → ((2)x, (2)y).
X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)
Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)
Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

What is your total pay for a week in which you
filled the following number of cartons?
Mon-210
Tues-175
Wed-224
Thurs-160
Fri-216
Sat-90
Answer:
$872.70
Step-by-step explanation:
Add all numbers from Mon-Fri.
So 985.
Multiply it by 0.78
So $768.30
Add 0.78 and 0.38
So 1.16
Then multiply 90 by 1.16
So $104.40
Then add the two numbers.
768.30+104.40
So $872.70
