2/5+7/15 in its simplest form
Answer:
13/15
Step-by-step explanation:
First convert the fractions to have a common denominator
2/5 = x/15
Cross multiply
2 × 15 = 5 × x
30 = 5x
Divide both sides by 5 to isolate the variable
30 ÷ 5 = x
6 = x
Plug x into the new fraction
6/15
Now add this to the other fraction
6/15 + 7/15
Only add the numerators. The denominators will remain the same number
6 + 7 / 15
13/15
It cannot be reduced anymore so this is simplest form

Find the amount and compound interest on 5000 at 6% per annum for 3 years annual
Answer:
The amount is 5,955.08
Step-by-step explanation:
Here, we want to calculate compound interest
We can find this by using the compound interest formula
A = P( 1 + r/n)^nt
A is amount
P
is the principal = 5,000
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times per year in which the interest is compounded = 1
t is the number of years = 3
Substituting these values;
A = 5,000(1 + 0.06/1)^3(1)
A = 5000(1.06)^3
A = 5,955.08
What is the slope of the line?

Carmen needed 23 of a yard of fabric to make a shirt and a 12 yard of fabric to make a matching skirt. How much total fabric did Carmen need to buy? 1 yard of fabric 1 yard of fabric 34 yard of fabric , 3 fourths, yard of fabric 116 yards of fabric , 1 and 1 sixth, yards of fabric 56 yard of fabric
Answer:
38/3 yards
Step-by-step explanation:
Given that,
Fabric required to make a shirt = 2/3 of a yard
Fabric required to make a skirt = 12 yards
Total fabric needed,
[tex]x=\dfrac{2}{3}+12\\\\=\dfrac{38}{3}\ yards[/tex]
Hence, 38/3 yards of fabric is needed.

Colton solved an equation incorrectly, as shown below:
Step 1: x - 13 = 26
Step 2: x = 26 - 13
Step 3: x = 39
Which statement best explains why Step 2 is incorrect in Colton's solution? (4
points)
He did not divide 26 by 13.
He did not multiply 26 by 13.
O He did not subtract 13 from 26.
He did not add 13 to 26.
Answer:
He didn't add 13 to 26
Step-by-step explanation:
he would need to add -13+13 to get rid of it. and add 13 on the other side 13+26
He added instead of subtracting. The answer is the first.
what is uv + v u = –1 and v = –1.
Answer:
u=1/2
Step-by-step explanation:
if v=-1 then v is multiplying u, -u+ -u which gives -2u. to find u, divide both sides by -2 .-1/-2 the negative cancels the negative giving you positive number, which is 1/2

A map has a scale of 1/2 inch =75 miles.If two cities are 3 3/4 inches apart,how many miles apart are they really
Answer:
3 3/4 inches = 562.5 miles
Step-by-step explanation:
Given that,
1/2 inch = 75 miles
It means,
1 inch = (75×2) miles
= 150 miles
3 3/4 inches= 15/4 inches
So,
[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]
Hence, 3 3/4 inches is equal to 562.5 miles.

f(x) = 3x - 3
g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23

Solve for x. Round answer to the nearest tenth (0.1).
Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9
~
Answer:
9.9 is your answer
Step-by-step explanation:
by using Pythagoras law
p²+b²=h²
7²+7²=x²
x=√{2×49)=7√2or 9.9 is your answer
