Answer:
The sum of three times a number and 4
Answer:
<em>4x+7y≤250</em>
Step-by-step explanation:
<u>Inequalities</u>
Let's call:
x = number of small rides
y = number of big rides
Since each small ride costs 4 tickets, x rides cost 4x tickets.
Since each big ride costs 7 tickets, y rides cost 7y tickets.
The total number of tickets is the sum of both:
Total tickets = 4x+7y
The friends have 250 tickets, so the total tickets of the rides cannot be greater than the 250 tickets available, thus:
4x+7y≤250
Answer:
-x - 29
Step-by-step explanation:
-2(5x + 1) + 3(3x - 9) = First, distribute the numbers in the parenthesis
-10x - 2 + 9x - 27 = Then, combine like terms
(-10x + 9x) + (-2 - 27)= Next, distribute the digits
-x - 29
Answer:
(32,92) and (−1,2)
Step-by-step explanation:
You have to equal the two Ys, meaning their values as well or you can find the value of the first x and then plug it in the second equation. There are many ways to solve this to.
The Simplification of the following expression is;
- x = 3
- m = -30/7
- v = -8.8
- x = 3
- u = -2.49
- a = -3/70
- p = -5
- t = 9
<h3>Simplification</h3>
2.1x - 1 - 4.2x = 5.3
2.1x - 4.2x = 5.3 + 1
- 2.1x = 6.3
x = 6.3/-2.1
x = 3
7/8m - 4/7 - 5/6m = - 3/4
7/8m - 5/6m = -3/4 + 4/7
21m-20m/24 = -21+16/28
1/24m = -5/28
m = -5/28 ÷ 1/24
= -5/28 × 24/1
= -120/28
m = -30/7
4.3v + 10.75 - 4v = 8.11
0.3v = 8.11 - 10.75
0.3v = -2.64
v = -2.64/0.3
v = -8.8
9/7 + 9/7x - 6/7x =0
9/7x - 6/7x = - 9/7
(9-6)x /7 = 9/7
3/7x = 9/7
x = 9/7 ÷ 3/7
= 9/7 × 7/3
= 9/3
x = 3
6.9u - 2 - 3.2u - 10 = 2.8
3.7u = 2.8 - 12
3.7u = -9.2
u = -9.2/3.7
u = -2.49
8/5 = - 4a + 7/5 - 2/3a
8/5 - 7/5 = -4a - 2/3a
8-7/5 = -12a-2a/3
1/5 = -14/3a
a = 1/5 ÷ -14/3
= 1/5 × -3/14
a = -3/70
8p + 6 - 4p = -14
4p = -14 - 6
4p = -20
p = -20/4
p = -5
7 - (5t - 13) = -25
7 - 5t + 13 = -25
-5t + 20 = -25
-5t = -25 - 20
-5t = -45
t = -45/-5
t = 9
