The sum of a number and two times a smaller number is 62 .Three times the bigger number exceeds the smaller number by 116 .
What is the biggest number and the smallest number??
Answer:
42,10
Step-by-step explanation:
let the numbers be x and y and x>y
x+2y=62
3x-y=116
multiply by 2
6x-2y=232
add the first
7x=294
x=42
from first
42+2y=62
2y=62-42=20
y=20/2=10

Step-by-step explanation:
9e + 4=5e + 14 + 13e
Answer:
e = -1
Step-by-step explanation:
1. 9e + 4 = 5e + 14 + 14e
2. 9e = 5e + 10 + 14e
3. 9e = 19e +10
4. -10e = 10
5. e = -1
Hope that helps
Answer:
e - 10
Step-by-step explanation:
1.) We need to manipulate the equation to get e by itself.
2.) To solve the equation, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e (Combine like terms)
9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)
e + 4 = 14 (Combine like terms)
e + 4 - 4 = 14 - 4 (Subtract 4 from each side)
e = 10 (Combine like terms.
3.) Answer: e = 10.
Now lets check our work. To check your work, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e
9(10) + 4 = 14 + 8(10)
90 + 4 = 14 + 80
94 = 94
By doing those steps we can confirm the answer, e = 10, is true.

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

Answer:
x = 1 , y =− 2
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of
x opposite.

The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?
Answer:
99inches
Step-by-step explanation:
The ratio of the sides of a triangle =2:4:9.
perimeter = 165 inches,
Total ratio= 2+4+9=15
perimeter = 165
Divide the perimeter by total ratio
165/15=11
Each of the sides
= (2×11) =22
(4×11) =44
(9×11)=99
the length of the longest side= 99inches
Find the missing length.
Answer:
Triangle 1 - 4
Triangle 2 - 10
Step-by-step explanation:
To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.
Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.
Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.
