Answer:
First, find any number that divides evenly into 360. Perhaps the number that comes to mind, since it ends in a 0, is 10. Since 10 divides into 360 and the result is 36, you can write 360 = 10*36.

Step-by-step explanation:
To win a trivia game, Nevan must score 90 points. Each correct
answer is worth 1 3/4 points, and each incorrect answer is worth
- 1/4 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
Nevan does not win
He scored 74 points
Step-by-step explanation:
First, find how many points he gets from 58 correct questions:
Multiply 1 3/4 by 58:
58(1.75)
= 101.5
Then, find how many points he loses from 22 incorrect questions:
Multiply -1 1/4 by 22:
22(-1.25)
= -27.5
Then, subtract 27.5 from 101.5 to find how many points he scored:
101.5 - 27.5
= 74
Since he needed 90 points to win, he did not win because he only got 74.

A car covers the distance between two cities in 6 hours. A van covers the same distance in 5.5 hours by travelling 4 km/h faster than the car. What is the distance between the two cities? Find the speed of the car and the van.
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given that,
A car covers the distance between two cities in 6 hours.
A van covers the same distance in 5.5 hours.
The speed of the van is 4 km per hour faster than the speed of car.
Let assume that
Speed of the car be x km per hour
So,
Speed of van is x + 4 km per hour.
Let further assume that
Distance between two cities be y km.
We know, Distance covered = Speed × Time.
➢ Now, Distance (y) covered by car at the speed of x km per hour in 6 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 6x}} - - - - (1)[/tex]
➢ Also, Distance (y) covered by van at the speed of x + 4 km per hour in 5.5 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 5.5(x + 4)}} - - - - (2)[/tex]
So, from equation (1) and (2), we have
[tex]\rm :\longmapsto\:6x = 5.5(x + 4)[/tex]
[tex]\rm :\longmapsto\:6x = 5.5x + 22[/tex]
[tex]\rm :\longmapsto\:6x - 5.5x = 22[/tex]
[tex]\rm :\longmapsto\:0.5x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{5}{10} \times x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{1}{2} \times x = 22[/tex]
[tex]\bf\implies \:x = 44[/tex]
On substituting the value of x, in equation (1), we have
[tex]\rm :\longmapsto\:y = 6 \times 44[/tex]
[tex]\bf\implies \:y = 264[/tex]
So,
[tex]\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:\begin{cases} &\sf{Distance \: between \: cities = 264 \: km} \\ \\ &\sf{Speed \: of \: car \: = \: 44 \: km \: per \: hour}\\ \\ &\sf{Speed \: of \: van \: = \: 48 \: km \: per \: hour} \end{cases}\end{gathered}\end{gathered}[/tex]

The Equation of line u is y =-8/9x+5/4. The equation of line v is y =9/8x+7/4. Are line u and line v parallel or perpendicular?
Answer:
when two lines are parallel the two slopes are equal (m1 =m2)
when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)
m1 =1st slope
m2= 2nd slope
using the formula y= mx +c
m1= -8/9
m2= 9/8
since m1 is not equal to m2 and -8/9 × 9/8 = -1
It is perpendicular

hello,i need help with this question:
The sum of the measures of angle M and angle R is 180⁰.
• The measure of angle M is (5x+10)⁰.
• The measure of angle R is 55⁰.
What is the value of x?
☺
Answer:
x = 23
Step-by-step explanation:
If the sum of angles is equal to 180 then we can write and equation to find the value of x
5x + 10 + 55 = 180 add like terms
5x + 65 = 180 subtract 65 from both sides
5x = 115 divide both sides by 5
x = 23

to add fractions what you want to do is this:
so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)
so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.
15+1 2/8=16 2/8
16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)
16 1/4
do the same with the other adding ones.
23 1/6+8 3/4=23 11/12
15 2/5+ 2 2/6= 17 11/15
now, do the same way as showed before but except subtract.
9/10 - 3/5 = 15/50
7 3/4 - 5 5/8 = 1/8
20 5/8= 1/8
What is 1/10=4/5y ?????
Answer:
y = 1/8
Step-by-step explanation:
Divide both sides by 4/5, 1/10 divided by 4/5; 4/5y divided by 4/5. In 4/5y divided by 4/5, the two 4/5s cancels out, leaving y alone. 1/10 divided by 4/5 equals to 1/8. Now you have, 1/8 = y, which is the same thing as y = 1/8. Therefore, the value of y is 1/8.
Answer: 1/8
Step-by-step explanation:
4/5y=1/10
*multiply both sides by 5, and you'll get
4y=1/2
*divide both sides by 4
y=1/8

Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
