Solve for b. 5b + 8 - 2b = 7b. A 2 B.4/5 C.4/7 D.1/2
Answers
Answer:
b=2
Step-by-step explanation:
5b + 8 - 2b = 7b
Combine like terms
3b+8 = 7b
Subtract 3b from each side
3b+8-3b = 7b-3b
8 = 4b
Divide each side by 4
8/4 = 4b/4
2 =b
Answer:
b=2
Step-by-step explanation:
Simplifying
5b + 8 + -2b = 7b
Reorder the terms:
8 + 5b + -2b = 7b
Combine like terms: 5b + -2b = 3b
8 + 3b = 7b
Solving
8 + 3b = 7b
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-7b' to each side of the equation.
8 + 3b + -7b = 7b + -7b
Combine like terms: 3b + -7b = -4b
8 + -4b = 7b + -7b
Combine like terms: 7b + -7b = 0
8 + -4b = 0
Add '-8' to each side of the equation.
8 + -8 + -4b = 0 + -8
Combine like terms: 8 + -8 = 0
0 + -4b = 0 + -8
-4b = 0 + -8
Combine like terms: 0 + -8 = -8
-4b = -8
Divide each side by '-4'.
b = 2
Simplifying
b = 2

Triangle E F G is shown. Angle G F E is a right angle. The length of G F is 3 and the length of E F is 4.6. Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.6 Over 3 EndFraction) m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction) m∠E = tan–1(StartFraction 4.6 Over 3 EndFraction)
Answers
Answer:
m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)
Step-by-step explanation:
Given the following
m<GFE = 90 degrees
GF = 3
EF = 4.6
The side opposite to m<E is GF
Adjacent side is EF
Using the SOH CAH TOA identity
tan theta = opp/adj
tan m<E =GF/EF
Substitute the given values
tan m<E = 3/4.6
m<E = tan^-1 (3/4.6)
Hence the required result is m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)

Helene invested a total of $1,000 in two simple-interest bank accounts. One account paid 8% annual interest; the other paid 9% annual interest. The total amount of interest she earned after one year was $86. Enter and solve a system of equations to find the amount invested in each account. Enter the interest rates in order as given in the problem. (Hint: Change the interest rates into decimals first.)
at 9%.
Answers
Answer: -600 and 1600 were invested into the two accounts.
Step-by-step explanation:
x = amount invested in the first account.
y = amount invested in the second account.
You start off with this equation
[tex]x + y = 1000[/tex]
[tex]0.08x + 0.09y=86[/tex]
Subtract both sides by y.
[tex]x=1000-y[/tex]
Subsitude 1000 - x for x for the second equation.
[tex]0.08(1000-y)+0.09y=$86[/tex]
Use the distributive property to solve for y.
[tex]80-0.08y+0.09y=86[/tex]
[tex]80-0.01y=86[/tex]
[tex]6=-0.01y[/tex]
[tex]=-600[/tex]
Subsitude -600 for y in the first equation and solve for x.
[tex]x-600=1000[/tex]
[tex]x=1600[/tex]
-600 and 1600 were invested into the two accounts.

8x2 – 4x = 363
Answers
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answers
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.
