Answer:
1
Step-by-step explanation:
In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.
Answer:
1
Step-by-step explanation:
-7-(-8)
First you should solve the brackets.Remeber (-) minus into (-) equal (+)therefore;
-7-(-8)= -7+8
when there is a minus and a plus you should minus the two numbers and put the largest value sign.therefore;
-7+8= 1
Hope you understand.If you have any problem just ask me I will solve it.
4 |m - n|
-if m = -7 and n= 2
Answer:
9
Step-by-step explanation:
I m - n I = I -7 - 2 I
{ Both are negative integers. So, add and result will have the negative sign}
= I -9 I
= 9
Answer:
-36
Step-by-step explanation:
We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.
To solve, we need to only substitute the values of each variable into the original equation :
4 |-7 - 2|
First solve the equation within the absolute value, any value that comes out of those brackets become positive :
|-7 - 2|
|-9|
4|-9|
4(-9)
Now multiply to get our answer:
4(-9)
-36

(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is
LCM(6, 4, 8) = 24
since 6×4 = 4×6 = 8×3 = 24. So
2/6 = (2×4)/(6×4) = 8/24
1 1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24
13 4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24
Then
2/6 + 1 1/4 + 13 4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12
(2) We have
LCM(12, 9) = 36
since 12×3 = 9×4 = 36. Then
121 2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36
781 6/9 = 7029/9 + 6/9 = 7035/9 = 2345/3
Find h. 10 cm h h = ✓ [?] cm .... 6 cm
Answer:
h²= G²- R²
h² = 10²-6²
h²= 100 - 36
h²= 64
h = √64
.............
Heya!
Answer:
h = √91 cm
Step-by-step explanation:
Apply pythagorean theorem, a² + b² ° c².
Where,
a = ½(6) = 3 cm
b = h
c = 10 cm
Plug in the values
3² + h² = 10²
9 + h² = 100
9 + h² - 9 = 100 - 9
h² = 91
h = √91 cm

There are 20 identical solid hemispheres. The curved surface and the flat surface of each hemisphereare are to be painted red and yellow respectively. Find the ratio of the amount of red paint needed to the amount of yellow paint needed.
Answer:
2:1.
Step-by-step explanation:
The area of a red curved surface = 2πr^2.
The area of the yellow flat surface = πr^2.
This is the case for all the hemispheres.
Therefore the required ratio = 2πr^2 : πr^2
= 2:1.

Find the equation of the line perpendicular to the 13x-3y=9 and passing through (-5,0)
9514 1404 393
Answer:
x +4y = -5
Step-by-step explanation:
The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.
3x +12y = 3(-5) +12(0)
3x +12y = -15
We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:
x + 4y = -5

Answer:
1 =b
Step-by-step explanation:
8 = b - 1 + 8b
Combine like terms
8 = 9b -1
Add 1 to each side
8+1 = 9b-1+1
9 = 9b
Divide each side by 9
9/9 = 9b/9
1 =b
Answer:
1
Step-by-step explanation:
Group like terms
8b + b = 8+ 1
simplify each sides
9b = 9
divide both sides by 9
9b÷9 = 9÷9
cancel out
answer is equal to 1
b = 1
