Answer:
z = 39
Step-by-step explanation:
Given
z - 18 = 21 ( isolate z by adding 18 to both sides )
z = 39
Answer:
z = 39
Step-by-step explanation:
z - 18 = 21
Add 18 to both sides;
z - 18 + 18 = 21 + 18
21 + 18 = 39
Hence,
z = 39

13. If l is parallel to m, find the values of x and y.
Answer: 14. x = 16; y = 23
15. x = 9; y = 13
Step-by-step explanation:
14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)
4x + 4 = 7x - 44
Collect like terms
4x - 7x = -4 - 44
-3x = -48
Divide both sides by -3
x = -48/-3
x = 16
39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)
39 + 8y - 43 = 180
Add like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23
15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)
15x - 26 = 12x + 1
Collect like terms
15x - 12x = 26 + 1
3x = 27
Divide both sides by 3
x = 27/3
x = 9
28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)
Plug in the value of x
28 + 12(9) + 1 + 4y - 9 = 180
28 + 108 + 1 + 4y - 9 = 180
Add like terms
128 + 4y = 180
Subtract 128 from each side of the equation
4y = 180 - 128
4y = 52
Divide both sides by 4
y = 52/4
y = 13

Solve the system of equation by elimination.
27= -3y + x
2 y=10 - 4x
Answer:
x=6 y=-7
Step-by-step explanation:
rearrange the equation
3y=x-27 eq 1
2y=-4x+10 eq 2
Multiply eq 1 by 2, and eq 2 by 3
6y=2x-54
6y=-12x+30 subtract the two eq's
0=14x-84
84=14x
x=84÷14
x=6
solving for y sub. x either eq 1 or 2
3y=x-27
3y=6-27
3y=-21
y=-21÷3
y=-7

Answer:Integers ={Positive Natuaral Number +Natural numbers having negative sign behind it+Zero}
={------,-3,-2,-1,0,1,2,3,..........}
Step-by-step explanation:
→Points marked on the X and Y axis on the Coordinate Plane=Integers only
→Point to be marked on the coordinate plane =(-0.5,2)
→As, points on both X and Y axis are integers only.To mark, -0.5 , mark a line between , 0 and -1,that will be ,-0.5.
→You can mark , any terminating decimal on the number line, which is marked with integers only.
→Terminating decimals are those decimals having in the denominator of a fraction.
So, to plot any terminating Decimal on the coordinate plane, you have to use property of Rational Numbers ,which is, you can find infinite number of terminating Decimal between two terminating Decimal.
→Mark -0.5 between 0 and -1 on the X axis.Similarly, mark integer 2 on the Y axis.Draw a line parallel to Y axis ,passing from (-0.5,0) and line parallel to X axis passing through (0,2).The intersection of these two lines will be required point (-0.5,2).

Step-by-step explanation:
A florist sells a bouquet of roses
for $16 each and a bouquet of carnations
for $10 each. The shop sells 28 bouquets
today and makes $400. How many bouquets of
roses did the shop sell today and how many
bouquets of carnations were sold today?
Answer:
Bouquets of roses = 20
Bouquets of carnations = 08
Step-by-step explanation:
Let,
x be the bouquets of roses sold
y be the bouquets of carnations sold
According to given statement;
x + y = 28 Eqn 1
16x + 10y = 400 Eqn 2
Multiplying Eqn 1 by 16
16(x+y=28)
16x + 16y = 448 Eqn 3
Subtracting Eqn 2 from Eqn 3
(16x+16y)-(16x+10y) = 448 - 400
16x + 16y - 16x - 10y = 48
6y = 48
Dividing both sides by 6
[tex]\frac{6y}{6}=\frac{48}{6}\\y=8[/tex]
Putting y=8 in Eqn 1
x + 8 = 28
x = 28 - 8
x= 20
Hence,
Bouquets of roses = 20
Bouquets of carnations = 08
find the value of x. round the lengths to the nearest tenth

use the trigonometry mnemonic (new monic) to help remember how sin cos and tan fit on the triangle
since you know the angle and you want to know the side opposite of that angle... and you know the side adjacent ( next to) the angle... use Tan
use the mnemonic to help
Tan(Ф)= Opp/ Adj ( we know two of these things and we want the 3rd :P )
Adj * Tan(25) = Opp
250 * Tan(25) = Opp
116.5769.... = Opp

John bought a shirt on sale for 25% off the original price and another 25 % off the discounted price. If the final price was $16, what was the price before the first discount?
Answer: original price = p
price after first 24% discount = .75p
he second 25% discount reduces the already reduced price to .75*.75p = .5625p
So, if .5625p = 16,
p = 16/.5625 = $28.44
check:
25% off $28.44 = $21.33
25% off $21.33 = $16.00

108 is what percent of 72? p= %
Answer:
72 is what percent of 108? = 66.67.
Step-by-step explanation:
brainlest?
Answer:
66.67%
Step-by-step explanation:
step 1:We make the assumption that 108 is 100% since it is our output value.
step 2:We make the assumption that 108 is 100% since it is our output value we seek with X.
step 3:From step 1, it follows that $100\%=108$100%=108.
step 4:In the same vein, $x\%=72$x%=72.
step 5:This gives us a pair of simple equations:
$100\%=108(1)$100%=108(1).
$x\%=72(2)$x%=72(2).
step 6:By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
step 7:Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{72}{108}$x%100%=72108
$\Rightarrow x=66.67\%$⇒x=66.67%
Therefore, $72$72 is $66.67\%$66.67% of $108$108.
and thats how the answer is 66.67%
The area A of a rectangle is represented by the formula A = lw, where l is the length and w is the width. The length of the rectangle is 5. Write an equation that makes it easy to find the width of the rectangle if we know the area and the length. *
Answer: rearrange the formula A=lw and make the width the subject of the formula
