Answer:
x < 15
Step-by-step explanation:
we want to isolate x, so we get rid of the 3, that is being divided by 2x, we take it to the other side to multiply.
2x < 10 x 3
2x < 30
we move the 2 that is multiplying x to the other side, since it was multiplying, we make inverse operations and now the 2 will divide 30
x < 30 ÷ 2
x < 15
Answer:
x=15 or false
Step-by-step explanation:
In order to find x you have to get the x by itself. To do this you multiply 3 on both sides this gives you 2x<30. Then you divide by 2, this gives you x=15. Then in order to find whether or not the inequality is true you have to plug x back in. 2(15)/3<10 is equal to 30/3=10 which leads to 10<10, which is false.

Cheddar cheese costs $4.25 per pound. Which equation best represents y, the total cost of x pounds of cheddar
cheese?
A. x = 4.25 + y
B. x = 4.25y
C. y = 4.25+ x
D. y = 4.25x
I will MARK brainlist!
Answer:
D
Step-by-step explanation:
4.25 × the amount of cheese you buy (x) equals the total cost (y)
Answer:
D. y = 4.25x
Step-by-step explanation:
You multiple the price per pound by the number of pounds. Can I have brainliest? Thanks!
Find the value of x please
Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔

the value of a second-hand car is £8000
Each year it loses 20% of it value at the start of this year. work out its value in 5 years time.
pls show working out
I will mark brainest and rate 5 stars
Answer:
£2,621.44
Step-by-step explanation:
Original cost of car = £8000
If it looses 20% of its value yearly
Value at the end of first year
80% * 8000
= 0.8 * 8000
= 6400
Value at the end of second year
80% * 6400
= 0.8 * 6400
= 5120
Value at the end of third year
80% * 5120
= 0.8 * 5120
= 4096
Value at the end of fourth year
80% * 4096
= 0.8 * 4096
= 3,276.8
Value at the end of fifth year
80% * 3,276.8
= 0.8 * 3,276.8
= 2,621.44
Hence the value in 5 years time will be £2,621.44
Solve each equation mentally for x.
5/2 • x = 1
Your answer must be in the form of a fraction.
You need to get x by itself to solve
So to get rid of 5/2, you need to multiply both sides by the reciprocal or 2/5...
5/2*2/5 = 1 which we don't write and 1*2/5 = 2/5
So now you'd have x =2/5

Answer:
For the second question, 4 busses and 3 cars.
Step-by-step explanation:
It's really simple actually, but sorry I can't come up with an equation. You can just add or multiply students per bus and students per car until you get to 195. Each bus can hold 45 students, so 45 x 4 = 180. Each car can hold 5 students, so 5 x 3 = 15. In total, 15 + 180 = 195 students.

AD is the angle bisector of EAB. Solve for X
Answer:
A) 5.76
Step-by-step explanation:
By angle bisector property of a triangle, we have:
[tex] \frac{12}{10} = \frac{x}{4.8} \\ \\ \frac{12 \times 4.8}{10} = x \\ \\ x = \frac{57.6}{10} \\ \\ x = 5.76[/tex]

You are treating yourself this week-end to an afternoon at a paintball park. For three hours Paintball Excursions charges $30 to rent equipment and $15 for each box of paintballs used. On the other side of town, at Paintball USA, they do not charge for rental of equipment but charge $25 for each box of paintballs. Their sessions also last three hours. Write and solve an equation to find the number of boxes of paintballs you would have to use for both parks to charge the same amount.

There are 50 students in a class. If 14% are absent on a particular day, find the number of students present in the class. What percent were not absent?
Answer:
i THINK 43% but im not for sure
Step-by-step explanation:
14% of 50 is 7
so 50-7=43
43(percent there)+7(percent gone)=50 (number of students)
SO 43% is still there.

Solve for x and all the missing angles.
(-11+3y)
(34+Y)
(37+y)°
Answer:
y=24; Angle 1: 61 degrees; Angle 2: 58 degrees; Angle 3: 61 degrees
Step-by-step explanation:
-11+3y+34+y+37+y=180 The sum of all the angles in a triangle is 180 degrees.
60+5y=180 Combine like terms
5y=120 Subtract 60 from 180
y=24 Divide 120/5
Angle 1: -11+ 3(24)= 61 degrees
Angle 2: 34+24=58 degrees
Angle 3: 37 + 24= 61 degrees
