Answer:
228 I believe
Step-by-step explanation:
Input the values first
3[tex](7)^{2}[/tex] + [tex]9^{2}[/tex]
PEMDAS it so exponents first
Even though the 7 is in () it's being multiplied by 3 is exponent would still come first
3(49) + 81
147 + 81 = 228
Answer:
228
Step-by-step explanation:Take 7 and multiply it by itself. you get 49. times 49 by 3 you get 147. Take 9 and multiply it by itself. You get 81. 147 plus 81 = 228

Betty had 1/3 yard of ribbon. She used 1/2 of it. How many yards of ribbon did she use?
a. 6 yd
b. 1/6 yd
c. 2/3 yd
d 3/2 yd
Answer:
b. 1/6 yd
Step-by-step explanation:
When Betty used 1/2 OF the 1/3 yards she has she has to multiple those. It's easier to put it in a sentence in my opinion because then you can see the "of" in the sentence which means to multiply. Hope this helps!

1-4x/2x+1=4/1-5x
solve in quadratic equations
Answer:
I can only assume that the entire 1-4x is divided by 2x, and 4 by all of 1 - 5x. You can guarantee more accurate results by using brackets where appropriate. If I read that expression with the correct notation, it reads as [tex]1 - \frac{4x}{2x} + 1 = \frac{4}{1} - 5x[/tex].
Assuming instead that it's meant as [tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}[/tex], we can solve it as shown below, giving us x values of 1 and 3/20 (or 0.15).
Step-by-step explanation:
First let's reformat this to the usual ax² + bx + c format:
[tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}\\(1 - 4x)(1 - 5x) = 4(2x + 1)\\1 - 5x - 4x + 20x^2 = 8x + 4\\20x^2 - 5x - 4x - 8x + 1 - 4 = 0\\20x^2 - 17x - 3 = 0[/tex]
Let's solve it with the quadratic formula:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\\\\x = \frac{17 \pm \sqrt{-17^2 - 4\times 20 \times( -3)} }{2\times20}\\\\x = \frac{17 \pm \sqrt{289 + 240} }{40}\\\\x = \frac{17 \pm 23 }{40}\\\\x = 1, \frac{3}{20}[/tex]

1. Add 7/4 to both sides
2. Multiply both sides by 4.
The solution is 15.
Answer:
x = 15
Step-by-step explanation:
Given
2 = - [tex]\frac{7}{4}[/tex] + [tex]\frac{1}{4}[/tex] x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )

8. Syairra needs to take an Uber to get to
the airport. The Uber charges $5.00 for
the first mile, and then $3.00 for each mile
after that. If the total charge is $62.00,
then how far was Syairra's taxi ride to the
airport?
Answer: 20 miles
Step-by-step explanation:
Since the Uber charges $5.00 for the first mile you have to subtract that from the total which is 62.
62.00 - 5.00 = 57.00
Then you keep subtracting 3.00 from 57.00 or you can divide 57 by 3 because 57 is how much money is left and the Uber charges 3 dollars for each mile after the first.
57.00 divided by 3.00 is 19
Then add 1 to 19 which equals 20 miles. You add 1 to 19 because 19 is the amount of miles she goes but that doesn’t include the 1st mile.

For what value of q is the equation –13(q + 4) = 7q + 16 true?
Hello! :)
[tex]\large\boxed{q = -3.4}[/tex]
-13(q + 4) = 7q + 16
Distribute the coefficient outside of the parenthesis:
-13(q) - 13(4) = 7q + 16
Simplify:
-13q - 52 = 7q + 16
Isolate for q by subtracting 7q from both sides:
-13q - 7q - 52 = 7q - 7q + 16
-20q - 52 = 16
Add 52 to both sides:
-20q - 52 + 52 = 16 + 52
-20q = 68
Divide both sides by -20:
-20q / (-20) = 68 / (-20)
q = -3.4
⠀⠀⠀⠀
The value of q is -3.4⠀⠀⠀⠀

➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :➠ - 13 ( q + 4 ) = 7q + 16
➠ -13q - 52 = 7q + 16
Now, we will bring the variable on left hand side and constants on right hand side
➠ -13q - 7q = 52 + 16
➠ -20q = 68
➠ q = 68/ -20
➠ q = 34/-10
As we have 10 in the denominator we can directly put the decimal .
➠ q = -3.4
∴ The value of q is - 3.4.
