(1) 2 of one step equations
x - 23 = 8
x - 23 + 23 = 8 + 23
x = 31
n + 2 = 9
n + 2 - 2 = 9 - 2
n = 7
(2) 2 equations with fractions
3/4 (x + 3) = 9
4 [ 3/4 (x + 3) ] = 4[9]
3 (x + 3) = 36
3x + 9 - 9 = 36 - 9
3x/3 = 27/3
1/3 x 3/4
cross multiply
so 3/12 and simplify which makes it
1/4
(3) distributive property
3(2 + 4) = (3 • 2) + (3 • 4)
3(6) = 6 + 12
18 = 18
Answer:
Step-by-step explanation:
This first step is to take the square root of the minus which is understood to be - 1
sqrt(-1) = i
So far what you have is
sqrt(-98) = i*sqrt(98)
sqrt(98) is just found the ordinary way
sqrt(98) = sqrt(7*7*2)
sqrt(7*7*2) = 7*sqrt(2)
Answer: 7 * i * sqrt(2) = i7*sqrt(2)
Pick the choice that looks like what you have done for homework.
Answer:
Sheldon have left 
of food.
Step-by-step explanation:
Quantity of food = 
kg
Quantity used on strawberry plant = 
Quantity used on tomato plant = 
Food left = Total - used on strawberry - used on tomato
Food left = 
Food left = 
Food left =
Therefore,
Sheldon have left of food.
Answer:
x = 105.4
Step-by-step explanation:
We are given;
Log 3 + log x = 5/2
We are required to find x;
We are going to use the laws of logarithms to solve for x
That is;
log a + lob b = log(ab)
Therefore;
Log 3 + log x = 5/2
we get;
log 3x = 2.5
But;
Given, logₐb= x , then b = a^x
In this case;
log 3x = 2.5
we get , 3x = 10^2.5
That is , 3 x = 316.227
x = 105.4
Thus, the value of x is 105.4
11/30 bags of mulch is needed.
<u>Step-by-step explanation:</u>
We have to find the number of bags of mulch.
7 (1/2) sq. yards need 2(3/4) bags of mulch.
So one sq. yd need 2(3/4) / 7(1/2)
We have to change the mixed fraction into improper fraction and then dividing them we will get the answer.
2(3/4) = ((2×4)+ 3)/4 = (8+ 3)/4 = 11/4
7(1/2) = ((7×2)+1)/2 = (14+1)/2 = 15/2
11/4 ÷ 15/2
It change into multiplication as,
11/4 × 2/15 = 11/30 bags of mulch is needed.
