Answer:
x=−5
Step-by-step explanation:
−3x+5=20
Step 1: Subtract 5 from both sides.
−3x+5−5=20−5
−3x=15
Step 2: Divide both sides by -3.
−3x/-3 = 15/-3

Two high schools are going on a field trip. One rents 8 vans and 9 buses for 228 students. The other rents 4 vans and 5 buses for 124 students. How many people can you fit in a van? How many people can you fit in a bus?
Answer:
No. pp you can fit in a van: 6,
No. pp you can fit in a bus: 20
Step-by-step explanation:
Let v = # of pp in vans, and let b = # of pp in buses:
8v + 9b = 228,
4v + 5b = 124
If we solve this system of equations by substitution, we isolate the first eq. for v and then substitute into the bottom eq:
v = 228-9b/8,
Substitute v = 228-9b/8 into bottom eq:
[4 * 228-9b/8 + 5b = 125]
[228+b/2=124]
[228+b = 248]
[b = 20]
Now substitute 20 to find no. of pp in the vans:
v = 228 - 9(20)/8 = 228 - 180/8 = 48/8 = 6

Combine any like terms in the expression. If there are no like terms, rewrite the expression.
6pg + 5pg - 6pg
Answer: I believe the answer is just 5pg?
Step-by-step explanation: Hope this helps but sorry if it's wrong. Not sure if I'm understanding the question correctly.
Answer: 5pg
Step-by-step explanation:
Like terms are terms that have the same variables and powers. E.g. 8p²g+9p²g=17p²g
8+9=17
8pg+9pg=17pg
8pg²+9pg²=17pg²
How to work out the question:
6pg+5pg=11pg
11pg-6pg=5pg

pls help me ASAP!! what is the surface area of this design? a) 288in b) 256in c) 96in d) 160in
Answer:
b) 256 inches
Step-by-step explanation:
8x5x2 = 80 (top & bottom)
8x5x2 = 80 (front & back)
8x8x2 = 128 (gross area of 2 sides)
4x4x2 =32 (delete this for side cutouts) Guessing the cutoff dimension on

https://brainly.com/question/11665146
Answer:
We know
y = 3.5x represents the cost of x pounds of raisins.
Also, cranberries costs $18 per 4 pounds
So, to graph these proportions, we have to find the equation for cranberries, if 4 pounds costs $18, that means 1 pound of cranberries is $4.50, this is the ratio of change of cranberries, using this ratio, we can say that the relation is
y = 4.5x
If you compare, cranberries are more expensive than raisins, the image attached shows both proportion graphed.
Therefore, raisins represent the lower unit price, $3.50 per pound, while cranberries represent the higher unit price, $4.50 per pound.
Answer :
well one line takes the slope of y=3.5x
The cranberries take the slope of Y=4.5x
so raisins have the lowest unit price.
Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
help quickly
Answer:
£3692
Step-by-step explanation:
A = p(1 + r/n)^nt
Where,
A = future value
P = principal = £2350
r = interest rate = 4.2% = 0.042
n = number of periods = 1(annual)
t = time = 4 years
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Total years = 10
Remaining years = 10 - 4
= 6 years
Remaining 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692
Maggie says that if the expression was 12÷3to the second power, you would divide before simplifying 3 to the second power. Is she right? Explain
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 before dividing.
I hope this helps!

a) Jelaskan konsep Alam Melayu.
Answer: The Malay world or Malay realm, is a concept or an expression that has been utilised by different authors and groups over time to denote several different notions, derived from varied interpretations of Malayness, either as a racial category, as a linguistic group or as a political-cultural group. The use of the term 'Malay' in much of the conceptualisation is largely based on the prevalent Malay cultural influence, manifested in particular through the spread of the Malay language in Southeast Asia as observed by different colonial powers during the Age of Discovery.

A donut shop made 32 donuts with frosting and 18 donuts without frosting. What is the ratio of the number of donuts with frosting to the number of donuts without frosting?
Answer:
16 to 9
Step-by-step explanation:
Represent donut with frosting with D1 and donut without frosting with D2.
So, we have:
[tex]D_1 = 32[/tex]
[tex]D_2 = 18[/tex]
Required
Find the ratio of D1 to D2
This is calculated as:
[tex]D_1 : D_2[/tex]
Substitute values for D1 and D2
[tex]D_1 : D_2 = 32 : 18[/tex]
Divide by 2
[tex]D_1 : D_2 = 32/2 : 18/2[/tex]
[tex]D_1 : D_2 = 16 : 9[/tex]
The ratio of donuts with frosting to donuts without is 16 to 9

Answer:
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Step-by-step explanation:
This function can be written as:
[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]
[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x). This implies that the denominator is the cosine of the angle whose sine is 1/(2x)
Think of a right triangle and consider the angle with this sine. Then the opposite side has length 1 and the hypotenuse has length 2x. The Pythagorean theorem then implies that the adjacent side is
[tex]\sqrt{4x^{2} -1}[/tex]
The cosine of the angle is adjacent over hypotenuse, so the cosine is
[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]
The secant is the inverse of the cosine, so the answer is
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
