Create a real world equality problem, then solve:
Example Problem:
Ana sells at least 220 shirts:
Ana Sold 85 shirts in the first 3 weeks of the month:
How many shirts must Ana sell in the last week of the month?
Solution:
Let S = the number of shirts Ana sells in the last week of the month.
Total Number of Shirts for the month must be greater than 220:
We Write: 85 + S ≥ 220
We Solve the inequality by Subtracting 85 from both sides: S ≥ 135
Therefore, Ana must sell 135 or more shirts in the last week to go on the school trip.
Solve: 85 + s ≥ 220 ========> S ≥ 135
Let's solve your inequality step-by-step.
85 + s ≥ 220
Step 1: Simplify both sides of the inequality.
s + 85 ≥ 220
Step 2: Subtract 85 from both sides.
s + 85 − 85 ≥ 220 − 85
s ≥ 135
Answer:
s ≥ 135
Check Problem:
85 + s ≥ 220 ========> S ≥ 135
We see that =====> 85 + 135 = 220
If Ana sells 135, or more shirts, The total number of shirts she sells that month will be 220 or more ========> Answer Checked
Hope that helps!!!!!!!!!!! : )
Answer:
30 degrees
Step-by-step explanation:
We know that the angle is going to be half of the minor arc it encompasses.
Since the minor arc is 60 degrees, the angle is 30 degrees!
Answer:
Diapers costs $11 and formula is $13.
Step-by-step explanation:
Let's name diapers as A and formula as B.
Simply the equations:
1A + 2B = $37(1)
2A + 5B = $87(2)
Clear D from one equation.
A = $37 - 2B(1)
Replace D into the other equation.
2*($37 - 2B) + 5B = $87(2)
$74 - 4B + 5B = $87
$74 + B = $87
B = $87 - $74 = $13
Find A, now knowing B.
A = $37 - 2($13)
A = $37 - $26 = $11
Answer:
Cost of a bag of diapers is $11 and cost of one can of formula is $13.
Step-by-step explanation:
Let cost of each diaper = $D and cost of each cans of formula = $C
Malik shops a bag of diapers and 2 cans of formula.
He spends total of $37.
So the equation will be
D + 2C = 37 -------(1)
Next week he stops and buys 2 bags of diapers and 5 cans of formula.
He spends total $87.
Equation for this purchase will be
2D + 5C = 87 ----------(2)
Multiply equation (1) by 2 and subtract it from equation (2).
2(D + 2C) - (2D + 5C) = 2×37 - 87
2D + 4C - 2D - 5C = 74 - 87
-C = - 13
C = 13
From equation (1)
D + 2×13 = 37
D + 26 = 37
D = 37 - 26
D = 11
Therefore, cost of a bag of diapers is $11 and cost of one can of formula is $13.
