Answer:
X = 7
Step-by-step explanation:
-11x - 6 + 20x = 57 (Collect like terms)
9x - 6 = 57 (Add 6 on both sides)
9x = 63 (Divide by 9 on both sides)
x = 7
(PLUG IN)
-11(7) -6 + 20(7) = 57
-77 - 6 + 140 = 57
-83 + 140 = 57
57 = 57 √

6x-4=3x+4 i need help doing this
Answer:
x=2.666 repeated
Step-by-step explanation: this is correct, pls mark brainliest. take -4 and add it to the other side(+4). 6x=3x+8. subtract 3x from 6x. 3x=8. take 3x and devide it on bolth sides. x=2.666 repeated
Answer:
x = 3/8
Step-by-step explanation:
6x -4 = 3x + 4
Step 1 - Add 4 on both sides
6x -4 = 3x + 4
+ 4 + 4
6x = 3x + 8
Step 2 - Subtract 3x on both sides
6x = 3x + 8
-3x -3x
3x = 8
Step 3 - Divide 3 on both sides
3x = 8
÷3 ÷3
Answer - x = 3/8

The ratio of books
to magazines in the
children's section at the
library is 5-2. If there
are 225 books, calculate
the number of
magazines.
50 magazines
because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50
There are 64 magazines in the library.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
The ratio of books to magazines in the children's section at the library is 5: 2.
Let number of books = 5x
And, Number of magazines = 2x
Here, There are 225 books in the library.
Hence, We can formulate;
⇒ 5x + 2x = 225
⇒ 7x = 225
⇒ x = 32
Hence, Number of magazines = 2x
= 2 × 32
= 64

Sketch a graph of the function f(x) = - (x+2) (x-4) (x-6) by finding the zeroes and determining
the sign of the values of the function between zeroes.
On her first day in a hospital, Kiri receives u1 milligrams (mg) of a therapeutic drug. The amount of the drug Kiri receives increases by the same amount, d, each day. On the seventh day, she receives 21 mg of the drug, and on the eleventh day she receives 29 mg.
a. write down an equation, in the terms u1 and d, for the amount of the drug that she receives on the seventh day.
b. write down an equation, in terms of u1 and d, for the drug that she receives on the eleventh day.
c. write down the value of d and the value of u1.
Answer:
a. 21 = u1 + 6·d
b. 29 = u1 + 10·d
c. d = 2, u1 = 9
Step-by-step explanation:
a. The given parameters are;
The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams
The amount of drug increase received by Kiri each day = d
The amount of drug Kiri received on the seventh day = 21 mg
The amount of drug she received on the eleventh day = 29 mg
Therefore, we have an arithmetic progression with the formula for the nth term given as follows;
aₙ = a₁ + (n - 1)·d
Where;
a₁ = u1
n = The number of terms
Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;
a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21
The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;
21 = u1 + 6·d
b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;
a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29
Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the eleventh day is given as follows;
29 = u1 + 10·d
c. Therefore, we have two equations which are given as follows;
21 = u1 + 6·d................(1)
29 = u1 + 10·d..............(2)
Subtracting equation (1) from equation (2) gives;
29 - 21 = (u1 + 10·d) - (u1 + 6·d)
8 = 4·d
d = 8/4 = 2
d = 2
From equation (1), we have;
21 = u1 + 6·d = u1 + 6×2 = u1 + 12
21 = u1 + 12
21 - 12 = u1
∴ u1 = 9
d = 2, u1 = 9.
