Make a the subject of the formula:
2a+9b=4
Make w the subject of t=7w+3
Answer:
a = (4 - 9b)/2
w = (t - 3)/7
Step-by-step explanation:
2a + 9b = 4
2a= 4 - 9b
a = (4 - 9b)/2
t = 7w + 3
7w = t - 3
w = (t - 3)/7

Answer: D
Step-by-step explanation:
You can either calculate what the rates will give, or try to compare them :
We have 5, 1 (hidden), and 3 as denominators, so 8*3*1 = 24
We'll take that as denominator.
Bank A : [tex]2.35 = \frac{2.35*24}{24}=\frac{56.4}{24}[/tex]
Bank B : [tex]2\frac{1}{3}=\frac{1*2*8}{3*8}=\frac{16}{24}[/tex]
Bank C : [tex]2\frac{5}{8} = \frac{5*2*3}{8*3} =\frac{30}{24}[/tex]
Bank D : [tex]2.61=\frac{2.61*24}{24} = \frac{62.64}{24\\}[/tex]
And now, let's compare the numerators !
[tex]\frac{16}{24} < \frac{30}{24} < \frac{56.4}{24} < \frac{62.64}{24} \\Bank B < Bank C < Bank A < Bank D[/tex]

The exact circumference of a circle is 25π millimeters. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer: A = 490.63 mm^2
Step-by-step explanation: Hello! To find the area of a circle, you have to find the radius of the circle from the circumference given. The formula is Circumference/2(3.14) = Radius. To find the circumference, multiply 25 x pi, or 25 x 3.14. 25 x 3.14 is 78.5. Put 78.5 in the equation for the circumference. 78.5/2(3.14) = Radius
Simplify:
78.5/6.28 = 12.5
The radius is approximately 12.5.
The formula for the area of a circle is 3.14 x r^2 = A
Put 12.5 in for r or radius
3.14 x 12.5^2 = A, 12.5^2 = 156.25
3.14 x 156.25 = A
3.14 x 156.25 = 490.625
Rounded to the nearest hundredth is A = 490.63
Answer: hope this helps ♡
The approximate area of the circle is 49.736 mm²
Step-by-step explanation:
Area of circle = π × r²
To find the radius:
25 ÷ 3.14 = 7.96178343949 (← diameter d = 2r)
7.96178343949 ÷ 2 = 3.98089171974 (radius)
π × r² =
3.14 × 3.98089171974² =
3.14 × 15.8474988843 =
49.7611464967 ≈ 49.736
Use the conditional statement to answer the question.
If an angle measures 43°, then the angle is acute.
Are the statement and its inverse true?
A. The statement is true, but the inverse is false.
B. The statement is false, but the inverse is true.
C. Both the statement and its inverse are false.
D. Both the statement and its inverse are true.

Ali drove 585 miles in 9 hours.
At the same rate, how many miles would he drive in 13 hours?
Answer:
845 miles
Step-by-step explanation:
First let us find the speed ( rate ) using the below formula.
[tex]\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}[/tex]
[tex]\sf Speed=\frac{585 \:miles}{9 \:h}[/tex]
[tex]\sf Speed=65\:miles\: per\: hour[/tex]
They also said that, at the same speed he traveled for 13 hours.
So, now we have to find the distance.
For that, you can use the same formula by making the distance as the subject.
Let us find it now.
[tex]\sf Distance \:\:travellled=Speed\:*\:Time\:\:Taken\\\\\sf Distance \:\:travellled=65\:*\:13\\\\\sf Distance \:\:travellled=845 \:miles[/tex]
Due to the demand of their chicken sandwiches, Popeyes decided to change the price from $2.29 to $2.59. Express this change as a percentage.
A-12% increase
B-12% decrease
C-13% increase
D-88% increase
Answer: C
Step-by-step explanation: You can use the percent error formula if you know it or just do:
value 2 - value 1
x 100 = percent
absolute value of value 1
The correct option C-13% increase. The price of the chicken sandwiches percentage increased by 13%.
Explain the term percentage change?Finding the differences between the two values in such a time series, dividing the difference by the initial value, then multiplying by 100 are used to determine the percentage change here between two values. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.For the stated question;
Original price of the chicken = $2.29
Increased price of the chicken = $2.59.
Let x be the percentage increase:
Thus,
2.29 + x% of 2.29 = 2.59
2.29 + 2.29x / 100 = 2.59
229 + 2.29x = 259
2.29x = 259 - 229 = 30
x = 30 / 2.29 = 13.1
x = 13 % (approx)
Thus, the price of the chicken sandwiches increased by 13%.

Calculate the area of the regular pentagon below:
Answer: 858.55 in
Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.
Answer:
858.55
Step-by-step explanation:
Area of triangle = 1/2BH
1/2(22.3*15.4) = 171.71
Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.
171.1(5) = 858.55

Second Sheet: B) 33°
Third Sheet: B) 4 units
Step-by-step explanation:
First Sheet:
Shape AKGP is the same as VWQX, meaning that the answers will be the same. Angle X is equal to angle P, meaning that the answer is 95°
Second Sheet:
Triangle SRT is equal to PQB. This means that angle Q is equal to angle R which means our answer is 33°
Third Sheet:
Since shape MQRN is equal to PKSD, we basically know the answer. The answer is 4 units because PK is equal to MQ.

14 minus 3z as a phrase.
I'm in 6th grade doing algrebraic experssions.
I have a test tomorrow, so please help me!
Answer:
Step-by-step explanation:
Simplifying
14 + -3z = 0
Solving
14 + -3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, and all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + -3z = 0 + -14
Combine like terms: 14 + -14 = 0
0 + -3z = 0 + -14
-3z = 0 + -14
Combine like terms: 0 + -14 = -14
-3z = -14
Divide each side by '-3'.
z = 4.666666667
Simplifying
z = 4.666666667
Answer:
14 less than 3 times of a number(z)
