Answer:
- 8.25
Explanation:
let the unknown number be represented by x.
54 + 4x = 21
(subtract 54 from both sides)
4x = - 33
(divide both sides by 4)
x = - 8.25

Answer:
Area of triangle = 8.9
Area of parallelogram = 53.4 yd² (option A)
Step-by-step explanation:
✔️Area of the triangle = ½*base*height
base = 3 m
height = 5.9 m
Area of triangle = ½*3*5.9
Area of triangle = 8.85 ≈ 8.9 (nearest tenth)
✔️Area of parallelogram = base*height
base = 8.9 yd
height = 6 yd
Area of parallelogram = 8.9*6 = 53.4 yd²

The area of a triangle is 2x^2 - 11x + 15 square meters. The length of the base of the triangle is 2x-5
meters. What is the height of the triangle?
Answer:
of triangle =12base×height
Area of triangle =2x2−11x+15
base =2x−5
Plugging in the given;
2x2−11x+15=12(2x−5)×height
2x2−11x+15=2x−52×height
2x2−11x+151=2x−52×height
2(2x2−11x+15)=(2x−5)×height
4x2−22x+30=(2x−5)×height
4x2−22x+302x−5=height
Resolving the quadratic equation;
(4x2−22x+30)
Simplifying;
4x
Answer:
2x-6
Step-by-step explanation:
height : 2(2x^2-11x+15)/(2x-5)
(4x^2-22x+30)/(2x-5)
Δ/4 = 121 - 120 = 1
x1 = (11+1)/4 = 3
x2 = (11-1)/ 4 = 5/2
4(x-5/2)(x-3)
(4x-10)(x-3)/(2x-5)
2(2x-5)(x-3)/(2x-5)
2x-6
Proof
(2x-6)(2x-5)/2
2(x-3)(2x-5)/2
2x^2-5x-6x+15
2x^2-11x + 15

Students were asked to vote for the leisure activity they liked best. The data are shown in the table. A 2-column table with 5 rows. Column 1 is labeled Number of Votes with entries 18, 22, 34, 28, 8. Column 2 is labeled Leisure Activity with entries Reading, Watching movies, Playing video games, playing sports, Other. Which statements are true? Check all that apply. A total of 34 students voted. The longest bar on a bar graph would be for the “Playing video games” category. The bars for “Watching movies” and “Playing sports” would be the same length. It would be time-consuming to show the data in a line plot because the data values are large. A line graph could be used to effectively represent the data.

Step-by-step explanation:
Answer:
y=0
x=4/3
Step-by-step explanation:
6x+y=8
x =8-y/6
substitute 8-y/6 in second equation
42*8-y/6 +7y=56
7(8-y) +7y=56
56-y+ 7y=56
-y+ 7y=0
6y=0
y=0
6x+y=8
6x+0=8
x=8/6

What is the value of x ??
Answer:

Step-by-step explanation:
√(64÷√(98
please help thanks
and show work it would be deeply appreciated
Answer:
√(64÷√(98 = (4√2)/7
Step-by-step explanation:
The Sqrt(64) is equivalent to 8
And the Sqrt(98) is equivalent to Sqrt(49) x Sqrt(2) also known as 7 Sqrt(2)
Now since we can't have a Square Root at the denominator we multiply it by Sqrt(2) on both the numerator and denominator
We now have 8Sqrt(2)/14 which can be simplified to (4√2)/7

£760 is divided between Stephen, Bridget & Caroline so that Stephen gets twice as much as Bridget, and Bridget gets three times as much as Caroline. How much does Bridget get? £
Answer: Out of £750 and 3 bums
Caroline = 225
Bridget = 225 * 3 = 675
Step-by-step explanation:
Answer:
£228Step-by-step explanation:
Given:
Total = £760Stephen = s, Bridget = b, Caroline = cWe have equations:
s + b + c = 760b = 3cs = 2bSubstitute s with b and b with c as above into first equation:
2(3c) + 3c + c = 7606c + 4c = 76010c = 760c = 76Find b:
b = 3*76 = 228Bridget gets £228

Answer:
y=18 x=15
Step-by-step explanation:
1.
multiplyboth sides by 3
2(x-6)=18
divide both sides by 2
x-6= 9
add 6 on both sides
x=15
2.
add 6 on both sides
2/3y= 12
multiply both sides by 3
2y=36
divide both sides by 2
y=18

James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20. James has dimes
The question is incomplete:
James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?
a. $10.00
b. $6.20
c.$15.50
d.$25.00
Answer:
d.$25.00
Step-by-step explanation:
With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:
x+y=162 (1)
0.10x+0.25y=31.20 (2), where:
x is the number of dimes
y is the number of quarters
First, you can solve for x in (1):
x=162-y (3)
Then, you have to replace (3) in (2) and solve for y:
0.10(162-y)+0.25y=31.20
16.2-0.10y+0.25y=31.20
0.15y=31.20-16.2
0.15y=15
y=15/0.15
y=100
Finally, you have to replace the value of y in (3) to find x:
x=162-100
x=62
Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:
100*0.25=25
According to this, the answer is that James has $25 in quarters.
The distances and times from a track meet for four schools are shown.
School has the fastest average time per mile at the track meet.
Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]
For Eastbay Middle,
Average time per mile = [tex]\frac{42}{7}[/tex]
= 6 minutes per mile
For Northwest Middle,
Average time = [tex]\frac{25}{5}[/tex]
= 5 minutes per mile
For South Central Middle,
Average time = [tex]\frac{28}{4}[/tex]
= 7 minutes per mile
For West Middle,
Average time = [tex]\frac{48}{6}[/tex]
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer:
240
Step-by-step explanation:
1/5
0.75 = 3/4
1/5 + 3/4 = 19/ 20
1 - 19/20 = 1/20
therefore 12 mango equal 1/20
12 × 20 = 240
12/240 is the same as 1/20

Answer:
169 [tex]cm^2[/tex]
Step-by-step explanation:
The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.
(7) * (5) = (35)
(9) * (5) = (45)
(7) * (5) = (35)
([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)
([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)
Add up all of the values:
(35) + (45) + (35) + (27) + (27) = 169
