How to solve 2(5-4a)=-33?

1 answer:

3 0

2(5-4a)=-33

First, you need to distribute. Multiply the 2 by each number inside the parantheses.

(2*5) - (2*4a) = -33
10 - 8a = -33

Subtract 10 from both sides.
-8a = -43

Divide both sides by -8.
a = 43/8

Hi there!

We know that RST is an equilateral(all 3 sides the same length) triangle, and is therefore equiangular(all 3 angles the same value). Therefore, angle S and is equal to one-third of the triangle's angle measure.

180/3=60

60=7x+4

56=7x

x=8

What is log squared with a base of 4 with the exponent (x^2+x) and the whole thing is equal to 0.25. Find the domain of x and fi

alexandr1967 [171]

Answer:

X = 1 , -2

Step-by-step explanation:

Given in question as,

(log4(x² + x))² = 0.25

log4(x² + x) = 0.5

Applying log base property if log(a)X = b, then X =a^b

Or, x² + x = 4^0.5

x² + x = 2

x² + x - 2 = 0

x²+2x-x-2 = 0

(x + 2) (x - 1) = 0

So, x = 1 and -2 Answer

A fish tank has the shape of a rectangular prism. It has a length of 2 1/4 m, width of 7/8 m, and a height of 1 1/2 m. What is t

Andru [333]

Data:
l (lenght) = $2 \frac{1}{4} m$ = $\frac{9}{4}m$
w (widht) = $\frac{7}{8}m$
h (height) = $1 \frac{1}{2} m$ = $\frac{3}{2} m$
V (volume) = ?

Formula:
$V = l*w*h$

Solving:
$V = l*w*h$
$V = \frac{9}{4} * \frac{7}{8} * \frac{3}{2}$
$V = \frac{189}{64}m^3$

Transforming into a mixed fraction:

.....................189 |_64 → denominator
numerator←(61)....2.→Whole part

Stays like this: $2 \frac{61}{64}$

Therefore:
$V = \frac{189}{64}m^3\:\longrightarrow\:\boxed{\boxed{V=2 \frac{61}{64}m^3 }}\end{array}}\qquad\quad\checkmark$
