The answer would be $1,000
1,200 - 200 = 1,000
-4 1÷5 - (- 13 1÷10)
first we should turn these into improper fractions by multiplying the whole number by the denominator then add the numerator.
4 × 5 = 20 + 1 = 21
13 × 10 = 130 + 1 = 131
(-21/5) - (-131/10)
To subtract fractions we want to find a common denominator so we can multiply the numerator and denominator of (-21/5) by 2 to get (-42/10)
(-42/10) - (-131/10)
Since we are subtracting a negative, that becomes a positive
(-42/10) + 131/10
131 - 42 = 89
89/10
Now we can change it back into a mixed fraction:
8 and nine-tenths or 8 9÷10
Step-by-step explanation:
3q - 1 = 3(1) - 1 = 2
3q -1 = 3(2)- 1= 5
10/p = 2 10/p = 5
p= 5 p= 2 (5-2=3, so 10/p is correct)
q=5, 3(5) -1 = 14
10/p = 14
p = 0.71??
Answer:
Step-by-step explanation:
Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph.
