Answer:
[tex] x = 18 [/tex]
[tex] y = 7.5 [/tex]
[tex] z = 7 [/tex]
Step-by-step explanation:
✍️[tex] (8x - 7) + (3x - 11) = 180 [/tex] (consecutive interior angles are supplementary)
Solve for x
[tex] 8x - 7 + 3x - 11 = 180 [/tex]
Add like terms
[tex] 11x - 18 = 180 [/tex]
Add 18 to both sides
[tex] 11x = 180 + 18 [/tex]
[tex] 11x = 198 [/tex]
Divide both sides by 11
✅[tex] x = 18 [/tex]
✍️[tex] (2y + 23) = (4y + 8) [/tex] (alternate interior angles are congruent)
Solve for y
[tex] 2y + 23 = 4y + 8 [/tex]
Collect like terms
[tex] 23 - 8 = 4y - 2y [/tex]
[tex] 15 = 2y [/tex]
Divide both sides by 2
✅y = 7.5
✍️[tex] (2y + 23) + (3z^2 - 5) = 180 [/tex] (linear pair angles)
Plug in the value of y
[tex] (2(7.5) + 23) + (3z^2 - 5) = 180 [/tex]
[tex] (15 + 23) + (3z^2 - 5) = 180 [/tex]
[tex] 38 + 3z^2 - 5 = 180 [/tex]
Add like terms
[tex] 3z^2 + 33 = 180 [/tex]
Subtract 33 from each side
[tex] 3z^2 = 180 - 33 [/tex]
[tex] 3z^2 = 147 [/tex]
Divide both sides by 3
[tex] z^2 = \frac{147}{3} [/tex]
[tex] z^2 = 49 [/tex]
Square both sides
[tex] \sqrt{z^2} = \sqrt{49} [/tex]
[tex] z = 7 [/tex]
Point S is on line segment \overline{RT} RT . Given RT=4x,RT=4x, ST=5x-10,ST=5x−10, and RS=6,RS=6, determine the numerical length of \overline{ST}. ST .
Answer:
[tex]ST = 10[/tex]
Step-by-step explanation:
Given
[tex]RT =4x[/tex]
[tex]ST = 5x - 10[/tex]
[tex]RS = 6[/tex]
Required
Determine ST
Since S is on RT, we have that:
[tex]RT = RS + ST[/tex]
[tex]4x = 5x - 10 + 6[/tex]
[tex]4x = 5x - 4[/tex]
[tex]4x - 5x= - 4[/tex]
[tex]-x= - 4[/tex]
[tex]x= 4[/tex]
Substitute 4 for x in [tex]ST = 5x - 10[/tex]
[tex]ST = 5 * 4 - 10[/tex]
[tex]ST = 20 - 10[/tex]
[tex]ST = 10[/tex]

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+4y=-4
Answer:
Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3
Step-by-step explanation:
1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)
2) you then divide by 4 on both sides (it will become y=-3/4=4/3)
3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)

Last year's computer models were priced at $1,850. They are now discounted 20%. What is the new retail price to the nearest dollar of that computer? $370 $1,480 $1,510 $1,830
Answer:
$1480Step-by-step explanation:
Step one:
Given that the price last year was $1850
and now the discount is 20%
we first need to solve for 20% of $1850
=20/100*$1850
=0.2*$1850
=$370
This means that the price was reduced by $370
so the new retail price is calculated as
=$1850-$370
=$1480

A restaurant bought 36.5 pounds of beef from a store. The next month, the restaurant bought 71.3 pounds of beef and 21.5 pounds of chicken. How many pounds of meat did the restaurant buy
Answer:
129.3 pounds
Step-by-step explanation:
A restaurant bought 36.5 pound of meat from a store
The following month they also bought 71.3 pounds of meat and 21.5 pounds of chicken
Therefore the total pounds of meat bought by the restaurant can be calculated as follows
= 36.5 + 71.3 + 21.5
= 129.3 pounds
5(y + 2) = 6(y - 1)
Show work
Please and thank you
Answer:
5 ( y + 2) = 6 ( y - 1)
- distribute the number outside into the parenthesis by multiplying it with each value
5y + 10 = 6y - 6
- subtract like terms, in this case 5y and 6y
-y + 10 = -6
- isolate the variable ( y) by getting rid of 10 by subtracting it to both sides
-y = -16
-1y = -16
- isolate variable (y) by getting rid of the -1 next to it by dividing it to both sides
y = -16 / -1
y = 16

Step-by-step explanation:
Given:
ΔWZY
∠W = 2(∠Y) -5°
∠X = ∠Y +21°
Find:
∠X, ∠Y, ∠W
Solution:
Using angle measures in degrees, we have ...
∠X + ∠Y + ∠Z = 180
(∠Y +21) +∠Y + (2(∠Y) -5) = 180
4(∠Y) +16 = 180 . . . . . simplify
∠Y +4 = 45 . . . . . . . . . divide by 4

Answer: Use a math calculator it should help. If not sorry. :/
Step-by-step explanation:
The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count for a serving of food can be computed using the formula C=4h+9f+4p, where his the
of grams of carbohydrate contained in the serving, is the number of grams of fat contained in the serving, and is the number of grams of protein contained in the serving
A serving of a certain type of but contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. How many calones are in this serving of ruts?
There are calories [___] in this serving of nuts
Answer:
152 calories
Step-by-step explanation:
The calories count, composition of carbohydrates, fat and protein are related by;
C = 4h + 9f + 4p
where C, h, f, and p have there given meaning.
Given that the serving of a type of nut contains; f = 12 grams, h = 6 grams and p = 5 grams, then;
C = 4(6) + 9(12) + 4(5)
= 24 + 108 + 20
= 152
C = 152 calories
Therefore, there are 152 calories in the serving of the certain type of nut.

Markups The depth of water in a pond increases by 3% after a heavy rain. If the average depth of the water was 8.3 feet, what is the new depth?
Answer: 8.55 feet
Step-by-step explanation:
We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.

A yardstick casts a shadow of 24 in. At the same time a telephone pole casts a shadow of 20 ft 8 in. What is the height of the telephone pole, to the nearest inch? (1 yd = 36 in., and 1 ft = 12 in.)
Answer:
372 inches
Step-by-step explanation:
(1 yd = 36 in., and 1 ft = 12 in.)
1 yard stick = 24 in
This means , height of 36 inches casts a shadow of 24 Inches
At the same time a telephone pole casts a shadow of 20 ft 8 in
1 ft = 12 in
Hence,
Convey 20ft to inches
1 ft = 12 in
20 ft = 20 × 12 inches
= 240 inches
Total shadow of the telephone pole = 240in + 8 in = 248 = 248 inches
Hence,
Height/Length of shadow = Height/Length of shadow
36/24= x /248
Cross Multiply
24 × x = 36× 248
x = 36 × 248/24
x = 372 inches
The height of the telephone pole, to the nearest inch is 372 inches
