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.
Answer:
x = 3
Step-by-step explanation:
Solve for x over the integers:
5^(2 x - 3) = 125
Multiply both sides by 125:
5^(2 x) = 15625
15625 = 5^6:
5^(2 x) = 5^6
Equate exponents of 5 on both sides:
2 x = 6
All equations give x = 3 as the solution:
Answer: x = 3
Answer:
x=14 or 14x
Step-by-step explanation:
5*2=10
5*3=15
10x-15=125
+15=+15
10x=140
/10=/10
x=14
Answer:
3.5yd each
Step-by-step explanation:
Total yard to be shared = 7
Ratio to be shared= 1:1 since they share equally.
Therefore Carly share = 1/2 ×7 = 3.5 yd
Ramil share is same as Carly = 3.5yd
