Answer:
x + y = 49
y = x - 15
Step-by-step explanation:
The sum of 2 numbers is 49 means that x+y = 49. (The two numbers are x and y, and the sum of them are 49.)
The second number is 15 less than the first number, means that y = x - 15 (The second number is y, and it is 15 less than x, which is the first number.)
Therefore the equations will be
x + y = 49
y = x - 15
Answer:
Step-by-step explanation:
The sum of 2 numbers is 49
x + y = 49
The second number is 15 less than the first number.
y = x - 15
Michelle has a round lamp to which she wants to add beads. The diameter is 12.2 inches. What is the circumference?
Answer: 38.34 inches
Step-by-step explanation:
The lamp is round which means that the circumference can be calculated by the formula:
= Pie * diameter
Pie = 22/7
Diameter = 12.2
Circumference = 22/7 * 12.2
= 38.34 inches

After the 4th half life how much of the sample is left if the mass is 100g.
Answer:
[tex]\huge\boxed{\sf 6.25 \ g}[/tex]
Step-by-step explanation:
After every Half life , Half of the mass is left.
After 1st Half life = 100 g / 2 = 50 g
After 2nd Half life = 50 / 2 = 25 g
After 3rd Half life = 25 / 2 = 12.5 g
After 4th Half life = 12.5 / 2 = 6.25 g

What is the solution of x + 6 11
C. x –1
PLSS SHOW YOUR WORK PLSS
Answer: x < -1
Step-by-step explanation:
x + 6 < 5
x + 6 = 5
x = -1
x < -1
Now try to prove its correct
A number less than -1 is -2 so we'll try that.
x + 6 < 5
(-2) + 6 < 5
4 < 5
We can tell after substituting -2 for x, that the answer is correct
Oh and I changed the less than sign to an equal sign so it's easier to solve.
Does that help?

HELP PLEASE! DELTA MATH! THANKS!
Last year at a certain high school, there were 140 boys on the honor roll and 68 girls on the honor roll. This year, the number of boys on the honor roll increased by 5% and the number of girls on the honor roll increased by 25%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answer:
11.5
Step-by-step explanation:
Find new values:
140(1+0.05)=147
68(1+0.25)=85
Last Year This Year
Boys 140 147
Girls 68 85
Total 208 232
Find overall increase:
208(1+r)=232
1+r=1.115385
r=0.115385
Final Answer: 11.5%
The total number of students on the honor roll increased by 11.5%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:
1.05 x 140 = 147
The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:
1.25 x 68 = 85
Therefore, the total number of students on the honor roll this year is:
147 + 85 = 232
The percentage increase in the total number of students on the honor roll is:
((232 - 208) / 208) x 100% = 11.5385%
Rounding to the nearest tenth gives an answer of 11.5%.
Therefore, the total number of students on the honor roll increased by 11.5%.
