Answer:
Step-by-step explanation:
Solving (1):
Express as a unit ratio
This implies that, the second term must be 1. So, divide by 4
Solving (2):
Let the number be x.
x or equal to -3 means:
x or equal to 0 means:
So, we have:
and
Rewrite as:
and
Write together:
Answer:
8.5
Step-by-step explanation:
8.54.
4 < 4
round down.
8.5
Rule: whatever you do to the left side, you must do on the right side. This means when you minus 80 on the left, you must minus 80 on the right as this continues to equate the two sides.
The value of the variables based on the equation is illustrated below.
<h3>How to calculate the variables?</h3>
Based on the information given, it should be noted that an equation simply means a formula that can be used to express the equality of two expressions.
1x - 1 - 4.2x = 5.3
Collect the like terms
1x - 4.2x = 5.3 + 1
-3.2x = 6.3
x = -1.969
7/8m - 4/7 - 5/6m = - 3/4
Collect the like terms
0.875m - 0.5714 - 0.833 = -0.75
0.875m = -0.75 + 0.5714 + 0.833
0.875m = 0.6544
m = 0.6544/0.875
m = 0.748
4.3v + 10.75 - 4v = 8.11
Collect the like terms
4.3v - 4v = 8.11 - 10.75
0.3v = -2.64
v = -2.64/0.3
v = -8.8
9/7 + 9/7x - 6/7x = 0
Collect the like terms
9/7x - 6/7x = 0 - 9/7
3/7x = -9/7
x = -9/7 × 7/3
x = -3
6.9u - 2 - 3.2u - 10 = 2.8
Collect the like terms
6.9u - 3.2u = 2.8 + 12
3.7u = 14.8
u = 14.8/3.7
u = 4
8/5 = - 4a + 7/5 - 2/3a
Collect the like terms
4a + 2/3a = 7/5 - 8/5
4 2/3a = -1/5
14/3a = -1/5
a = -1/5 × 3/14
a = -3/70
8p + 6 - 4p = -14
Collect like terms
8p - 4p = -14 - 6
4p = -20
p = -20/4
p = -5
7 - (5t - 13) = -25
Collect like terms
-5t = -25 - 7 - 13
-5t = -45
t = -45/-5
t = 9
