Answer:
$3x+$5y=C and the total cost is $ 78
Step-by-step explanation:
the equation first is going to be $3x+$5y=C
x: small balloons
y: large balloons
c: total cost
Now to find the how much the total cost is, you should substitute the variables and then solve the equation.
x: 11
y:9
3(11)+5(9)= 33+45
78
Answer:
1:5
Step-by-step explanation:
Since 60 is divisible by 12, the answer of 5 would be used in ratio form too.
Answer:
section 3
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area above the solid line y=x/4
-----> inequality B
The solution of the inequality B is the shaded area below the solid line y=x-3
therefore
The solution of the system of inequalities is the shaded area in the section 3
see the attached figure
Answer:
a + b = 1 or 4
Step-by-step explanation:
The integer = 3a5b
The factors of the integer includes 5 and 6
∴ 5 × 6 = 30 is a factor of the integer hence 10 is also a factor which gives b = 0
We check for factors of four digit numbers with the first digit = 3, last digit = 0, penultimate to the last digit = 5 and divisible by 30
We have a50 divisible by 30, which gives, a5 divisible by 3 which includes
15 and 45 hence a can be 1 or 4 and a + b = 1 + 0 = 1 or 4 + 0 = 4.
