Answer:
X =8
Step-by-step explanation:
DF = DE + EF
15 = X+1 + X-2
16 = 2X
X = 8
the measure of the angles of a triangle are shown in the figure below. solve for x.
Answer:
90+33+7x+8 = 180 so 180-131 = 7x so 7x = 49 or x = 7.

Answer:
see explanation
Step-by-step explanation:
note that [tex]3^{p+1}[/tex] = [tex]3^{p}[/tex] × 3 ( when multiplying exponents are added )
Given
[tex]\frac{3^{p+1}-3^{p} }{2.3^{p} }[/tex] ← factor out [tex]3^{p}[/tex] on numerator
= [tex]\frac{3^{p}(3-1) }{2.3^{p} }[/tex]
= [tex]\frac{2.3^{p} }{2.3^{p} }[/tex]

Sylvie is mixing concrete for her patio. For every 26.7 pounds of concrete mix, she needs to add 1 quart of water. Sylvie buys 80 kilograms of
concrete mix
1 kilogram 2.2 pounds
How many quarts of water, rounded to the nearest tenth, does Sylvie need to add to 80 kilograms of concrete mix?
Step-by-step explanation:
that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.
so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.
she should add 1 quart of water to every 26.7 pounds of concrete mix.
80 kg = 80×2.2 pounds = 176 pounds.
we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.
176/26.7 = 6.5917603... quarts of water needed.
that would be rounded 6.6 quarts of water.

What’s the rate of change of the table above?
A) -1/3
B) 1/2
C) -1/4
D) 1/5
answer is option D
because you can divide them like
[tex] \frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5} [/tex]

Step-by-step explanation:
The sum of the digits of a two- digit number is 6. When we interchange the digits, the new number is 18 less than the original number. Find the original number.pls explain step by step
Answer:
42
Step-by-step explanation:
S1 let a and b be the digits of the number
so a 2 digit number cab written as - 10×a + b
eg - 68 as 6×10 + 8
S2 ) according to ques
a + b = 6 - eqn 1
(10×a + b) - (10×b + a) = 18
9×a - 9×b = 18
a - b = 2 - eqn 2
S3)from eqn 1 and eqn 2
we get a = 4 and b = 2
hence number is 42

What does transformation mean in math
Answer:
In mathematics, a transformation is a function f (usually with some geometrical underpinning) that maps a set X to itself, i.e. f : X → X. In other areas of mathematics, a transformation may simply refer to any function, regardless of domain and codomain.

84 + 4m = 276
What does M=
hi <3
84 + 4m = 276
subtract 84 from both sides:
4m = 192
divide both sides by 4:
m = 192/4 = 48
hope this helps :)
Hey there!
84 + 4m = 276
➡️ 4m + 84 = 276
SUBTRACT 84 to BOTH SIDES
4m + 84 - 84 = 276 - 84
CANCEL out: 84 - 84 because that gives you 0
KEEP: 276 - 84 because that helps solve for the m-value
276 - 84 = 192
NEW EQUATION: 4m = 192
DIVIDE 4 to BOTH SIDES
4m/4 = 192/4
CANCEL out: 4/4 because that gives you 1
KEEP: 192/4 because that helps you get the m-value
NEW EQUATION: m = 192/4
SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER
m = 48
Therefore, your answer is: m = 48

Answer:
∠ WOT = 85
Step-by-step explanation:
To find the measure of ∠WOT
we know that ∠UOV is 180 in the pic
so by letting ∠WOT = x
∠UOT + ∠WOT + ∠WOV = 180
30 + x + 65 = 180
95 + x = 180
x = 180-95
x = 85
so ∠ WOT = 85

Set up a proportion to solve for x in the following similar triangles,
12
15
8 X-4
Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
[tex]\frac{15}{x-4}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )
12(x - 4) = 120 ( divide both sides by 12 )
x - 4 = 10 ( add 4 to both sides )
x = 14
