Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]
A, O and B lie on a straight line segment where
A=24,B=40 C=31
i)AOB=
ii)ZOB=
iii)XOY=
iv)AOY=
v)YOZ=
Answer:
Step-by-step explanation:
AOB=180°
ZOB =c=31°
XOY=b= 40°
AOY= a+b =24+40 = 64°
YOZ =180-a-b -c=180-24-40-31=85°
Hope this helpsxx
Determine whether the given value of the variable is a solution to the inequality 3b + 2 < 14 when b = 4
Answer:
I dont think it that would be the solution because 14 has to be greater and not equal.
Step-by-step explanation:
3(b) + 2 < 14
3(4) + 2 < 14
12 + 2 < 14
14 < 14
Which of the following equations , in it's simplest form , will be equivalent to 3x+2+(-5)?
A: 2+3x+5. B: x-1+x-2+x C: -3-3x-1+x
D: 3-3x
Answer:
The correct answer would be B: x-1+x-2+x
Step-by-step explanation:
First, you would do 2+(-5), from the given equation. Then, it could be simplified to 3x-3. Then, looking at B, you would add the like terms, meaning you would add all the x´s together, and the whole numbers together, giving you 3x-3. I hope I made this easy to understand for you!

7/2x + 1/2x = 10 + 9/2x
Answer:
x=-1/20
Step-by-step explanation:
7/2x+1/2x=10+9/2x
We move all terms to the left:
7/2x+1/2x-(10+9/2x)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/2x+1/2x-(9/2x+10)=0
We get rid of parentheses
7/2x+1/2x-9/2x-10=0
We multiply all the terms by the denominator
-10*2x+7+1-9=0
We add all the numbers together, and all the variables
-10*2x-1=0
Wy multiply elements
-20x-1=0
We move all terms containing x to the left, all other terms to the right
-20x=1
x=1/-20
x=-1/20
Answer:
[tex] \frac{7}{2} x + \frac{1}{2}x = 10 + \frac{9}{2} x \\ ( \frac{7}{2} + \frac{1}{2} - \frac{9}{2} )x = 10 \\ \frac{ - 1}{2} x = 10 \\ - x = (10 \times 2) \\ x = - (10 \times 2) \\ x = -20[/tex]

Gia opened two savings accounts at two diffrent banks. One account earns an annual 3.4% simple interest, and the other earns half as much. If she deposited $509 in each account, how much total interests will sh have earned in 3 years? A:$153.00 B:$38.25 C:$76.50 D:$51.00
Interest from first account is :
[tex]I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918[/tex]
Interest form second account is :
[tex]I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 = \$25.959[/tex]
So, total interest is :
[tex]I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877[/tex]
Therefore, total interest is $77.877 .

Answer:
slope = 2
y-int = 3
Step-by-step explanation:
y-intercept can be determined by the coordinate (0,3) which is 3 units up from origin on the y-axis
slope can be determined by taking the difference of a pair of y-values and dividing it by the difference of the x-values
ex, 3 - 1 = 2
0 - (-1) 1
or: 5 - 3 = 2

what is the area of shape 1, 2 and 3
Answer:
Shape 1: 25.915
Shape 2: 102.85
Shape 3: 142
Step-by-step explanation:
For shape 1, you have to divide 7.1 to get half the width of the triangle. You get 3.55 from that, and then finding the triangle itself you have to do 7.3*3.55 to get 25.915. For shape 2, you first do the harder parts (the triangles) and since there is two of them we don't need to half the width of each triangle. But first to get the width, we need to do 20-17.4=2.6. But since there are 2 triangles we need to divide that by 2 to get 1.3. Then you multiply that by 5.5 to get the final area of both triangles which is 7.15. Next you simply find the rectangle which is 17.4*5.5=95.7. You add the triangles area to get 102.85. Finally for shape 3 you simply do 7.1*20=142.

f(x) = 16* and
19(x) = 161/2
related?
Answer:
F(x) = 16^x = 8^2x
g(x) = 16^1/2x = 8^x
So you can see the relationship. They are all of the type a^bx form, with same base of a, f(x) will have larger increasing rate.

An account with an initial deposit of 3,500 earns 7.25% annual interest, compounded continuously. How much will the account be worth after 30 years? Round to the nearest cent.
Answer: $28,575.05
Step-by-step explanation:
Formula: FV = (1+r/n)^nt
FV = future value of the deposit
P = principal or amount of money deposited
r = annual interest rate (in decimal form)
n = number of times compounded per year
t = time in years.
3,500(1+7.25%)^30=28,575.05468

Step-by-step explanation:
Edge 2020 assingment
Goodluck everybody!
∛2 is the radical part of both ∛54 and ∛128 when the expression are simplified.
What is Number system?A number system is defined as a system of writing to express numbers.
Let us write the prime factors of 54.
54/2 = 27
When fifty four is divided by 2 we get twenty seven.
27/3=9
Twenty seven divided by three is nine.
9/3=3
So 54 = 2 × 3 × 3 × 3
we know ∛ 3 × 3 × 3 = 3
∛54 = ∛ 3 × 3 × 3×2 = 3∛2
Hence, ∛2 is the radical part of both ∛54 and ∛128 when the expression are simplified.
