Answer:
x = 94/k
Step-by-step explanation:
kx-4=90
Add 4 to each side
kx-4+4=90+4
kx = 94
Divide each side by k
kx/k = 94/k
x = 94/k

Answer:
x = 12
Step-by-step explanation:
Here we go!
What we know:
So 7x and 8x are part of a same side interior angle. meaning, they add up to 180°!
[tex]8x + 7x = 180[/tex]
Combine like terms
[tex]15x = 180[/tex]
Divide 15 from both sides
[tex]x = 12[/tex]
Let's check our work:
plug in x
7(12) + 8(12) = 180
multiply
84 + 96 = 180
add
180 = 180

What do you call a relation where each element in the domain is related to only one value in the range by some rules?
The figure above shows a cement block of
36 cm x 20 cm x 9 cm with two 10 cm x 8 cm
openings. What is the weight of the cement block
to the nearest gram? (The density of cement is
1.7 gram/cm
cm)
A) 5,040
B) 6,048
C) 7,560
D) 8,568
Answer:
D) 8,568Step-by-step explanation:
weight = (volume of block - volume of slots) x density of block
= (30 * 20 * 9) - (2 x (10 * 8 * 9)) x 1.7
= (5400 - 1440) x 1.7
= 8,568
Volume is a three-dimensional scalar quantity. The correct option is D, 8568 grams.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the complete block is,
Volume = 36 cm x 20 cm x 9 cm = 6480 cm³
The volume of the opening is,
Volume of the opening = 2 × 10 cm x 8 cm × 9cm = 1440 cm³
Therefore, the weight of the cement block to the nearest gram is,
Weight = (6480 -1440)cm³ × 1.7 gram/cm³
= 8568 grams

-11x-6+20x=57
plz show work
Answer:
X = 7
Step-by-step explanation:
-11x - 6 + 20x = 57 (Collect like terms)
9x - 6 = 57 (Add 6 on both sides)
9x = 63 (Divide by 9 on both sides)
x = 7
(PLUG IN)
-11(7) -6 + 20(7) = 57
-77 - 6 + 140 = 57

What is the reason for Statement 2 of the two-column proof?
Ruler Postulate
Angle Addition Postulate
Angle Congruence Postulate
Linear Pair Postulate
Answer:
Linear Pair Postulate
Step-by-step explanation:
I took the test and this is the right answer.
Supplementary angles are two angles that add up to [tex]180^o[/tex]. The reason for statement 2 is Linear Pair Postulate.
From the given figure, we can see that:
[tex]\angle PQS[/tex] and [tex]\angle SQR[/tex] are on a straight lineThey both add up to [tex]180^o[/tex]When two angles have the above features, the two angles are said to be linear pairs, and they are supplementary.
Hence, the statement that complete the proof is (d) Linear Pair Postulate

© Stephen was thinking of a number. Stephen doubles it, then adds 11 to get an
answer of 47.7. What was the original number?
Answer:
18.35
Step-by-step explanation:
This is a question which requires you to work backwards.
Divide means multiply and vice versa
Addition means subtract and vice versa
First, we find the number before 47.7.
47.7-11=36.7
Secondly, we find the number before 36.7, aka the original number.
36.7/2=18.35 (/ sign means divide)
