Help please also give an explanation

Mathematics
1 answer:
natka813 [3]4 years ago
3 0

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

<h3>\frac{a + bc}{wd + f}  = g</h3>

<u>First of all cross multiply</u>

That's

g( wd + f ) = a + bc

<u>Multiply the terms at the left side of the equation</u>

We have

gwd + fg = a + bc

<u>Send fg to the right side of the equation</u>

That's

gwd = a + bc - fg

<u>Divide both sides by dg to make W stand alone</u>

<h3>\frac{gwd}{dg}  =  \frac{a + bc - fg}{dg}</h3>

We have the final answer as

<h2 /><h2>w =  \frac{a + bc - fg}{dg}</h2>

Hope this helps you

A stadium's normal ticket price is $78. As a special promotion they offer 15% off. What is the price of the discounted ticket?
alexgriva [62]
ANSWER: $66.30

WORK:
to find 15% off, multiply by 0.15.
78 x 0.15 = 11.7

note: this is the percent off, so it's subtracted to find the sale price. 

78 - 11.70 = 66.3

If a 100.8g cement bag has 20.35 kg removed from it. what is the new weight of the bag
kykrilka [37]

100.80 kg - 20.35 kg = 80.45 kg . . . . the new weight of the bag

It's a pretty straightforward subtraction problem. As with any decimal addition or subtraction, you line up the decimal points and extend any numbers with zeros to make the number of decimal places match.

Can someone solve this
Gemiola [76]

Answer:

f(h(-1)) = -1

Step-by-step explanation:

f(x) = (x-4)/3

h(x) = 3x + 4

f(h(-1)) = ?

So first off we need to solve for h(-1):

h(x) = 3x + 4

h(-1) = 3(-1) + 4

h(-1) = 1

Next, we plug this value into the f(x) equation:

f(x) = (x-4)/3

f(1) = (1-4)/3

f(1) = -1

f(h(-1)) may look confusing but it is just f(x) with x being the resulting value for h(-1)

Thus we can say that f(h(-1)) is equal to -1

Help!!!! for just 3 but if you know 4 also then it’s on my page and I would appreciate the help

A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first 
√625- 96   = √529
Now set up two equations
(10 + √529) ÷2   = x   = 16.5
(10 -  √529) ÷2   = x   = -6.5 
So therefore x = 16.5 and -6.5
