the measure of angle a is -2x+35 degrees. the measure of angle b is quadruple angle a. write an expression for their sum.
Answer:
= -10x + 175
Step-by-step explanation:
(4(-2x+35)) + (-2x+35)
= -8x+140 - 2x + 35
= -10x + 175
1.) Yvonne purchased $46 worth of items for a theme party. A small bag of party hats cost $2.75, a pack of napkins cost $3.50, and a set of cups and plates cost $2.00. If Yvonne bought 4 bags of hats, and 2 packs of napkins, how many cup and plate sets did she buy?
Answer:
14
Step-by-step explanation:
$46 in total
Hats: $2.75 * 4 bags = $11
Napkins: $3.50 * 2 packs = $7
11 + 7 = 18
$46 - $18 = $28
$2.00 / 28 = 14
If cups and plates were $2.00, that means it would take 14 sets to fill the remaining $28.

Step-by-step explanation:
Find the equation of the line with slope = -8 and passing through (9,-73). Write your equation in the form
y
=
m
x
+
b
y
=
m
x
+
b
.
Answer:
y = - 8x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = - 8 , then
y = - 8x + c ← is the partial equation
To find c substitute (9, - 73 ) into the partial equation
- 73 = - 72 + c ⇒ c = - 73 + 72 = - 1
y = - 8x - 1 ← equation of line

An item costs 340 before tax, and the sales tax is 20.40.
Find the sales tax rate. Write your answer as a percentage.
Answer:
Step-by-step explanation:
To find out the sales tax rate, we divide the sales tax by the cost of the item. This will give us what percent of the cost of the item the sales tax is equal to.
So, 20.4 divided by 340 = 0.06
To convert to percent, we multiply 0.06 by 100=6. Therefore, the sales tax rate is 6%.
Check:
340 times 0.06 (the sales tax rate) is 20.4 (the sales tax).
The average number of points a basketball team scored for three games was 63 points. In the first two games they scored the same number of points which was 6 points more than they scored in the third game. Write and solve an equation to find the number of points the team scored in each game.
Answer:
First Game: 65 points
Second Game : 65 points
Third Game : 59 points
Step-by-step explanation:
Average = sum of values/number of values
The number of values = 3, an d average = 63
63 = x/3
63 * 3 = x
189 = x
Now 189 is the sum of points over two games.
Their first two games are worth the same, so lets call that s +s = 2s
Their 3rd game is worth 6 less points than s, so s-6
let's add up all the terms:
2s + (s - 6) = 3s - 6
Solve:
3s - 6 = 189
3s = 195
s = 65
The first two games are worth 65, and the third game is worth 65 - 6 = 59.
-Chetan K
Answer:65, 65 and 59
Step-by-step explanation:
If represented by x and y, (2x+y)/3=63
So 2x+y=189
So if x=y+6
Put the value of x into the equation
2x + y = 189
2(y + 6) + y = 189
2y + 12 + y = 189
3y = 189 - 12
3y = 177
y = 177/3
y = 59
Therefore, x = y + 6 = 59 + 6 = 65
Maggie spent $4.05 dollars on cheese and fruit at the farmer's market. She bought 1/8 pound of apples,1/4 pounds of pears,and 1.25 pounds of bananas. If fruit cost $0.80 per pound ,how much did Maggie spend on cheese?
Total weight of fruit: 1/8 + 1/4 + 1.25 = 1.625 pounds
Cost of fruit: 1.625 x 0.80 = $1.30
Cost of cheese = total spent - cost of fruit:
Cost of cheese = 4.05 - 1.30 = $2.75
Answer: $2.75
Answer:
1+2=3
3×0.8=2.4
4.05-2.4=1.65

My teacher is teaching us how to put points into y - y1 = m ( x - x1) and she give us a set of points and a slope. But i don't know how to plot this one question in. The slope is unidentified and the set of points are (2,5). Ty!!
Answer:
Step-by-step explanation:
The point will be 2 on the x-axis and 5 on the y axis.
Answer:
I feel the question is incomplete but there's another formula (which we can only use if the points are the intercepts on the x and y axis)
x/a + y/b = 1( a= intercept on x axis ; b = intercept on y axis )
x/2 + y /5 = 1
multipy both sides by 10
5x + 2y = 10
2y = 10- 5x
divide both sides by 2
y = 5 - 5/2x
y = -5/2 + 5(the equation of the line if the two points are the intercepts on the both axis
If 4x - 9 = 35,
find the value of 6x + 4
Step-by-step explanation:
4x=44
x=11
6x+4= 6*11+4= 70
Answer:
6x+4=70
Step-by-step explanation:
To solve this, first, we need to know what x is. To do this, we need to solve the equation:
4x-9=35
The first step to solving this is to add nine to both sides, since we need to do the inverse of subtraction to get our answer.
4x-9+9=35+9
4x=44
Now, do the inverse of multiplying by four, which is dividing by four, to both sides.
4/4x=44/4
x=11
Now that we know what x is, we can find the value of 6x+4. Simply plug in 11 for x.
6(11)+4
66+4
70
Our answer is 70.

9. A tailor has 23 metres of cloth. She wants to make 7 baju kurung of the same size. She then has 2 metres of cloth left. How many metres of cloth did she use to make each baju kurung?
Answer:
The tailor used 3m per baju kurung.
Step-by-step explanation:
The tailor began with 23m of cloth and at the end had 2m of cloth left. You calculate how many meters of cloth she used all together by subtracting 2 from 23:
23m - 2m = 21m
Then you find out how many meters she used per baju kurung by dividing 21 by 7:
21m / 7m = 3m
Wen says the function is continuous, because the number of people is unlimited. Is Wen right or wrong?
Answer Wen is incorrect. The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.
