Answer:
The answer is 29
Step-by-step explanation:
5(7)-6 once you put it in the calculator you will get 29 as the answer for all of it. The w is 7 and when you place it next to the 5 you have to multiply it and then subtract it by the x which is the 6.
I hope this helps!
After substituting, the value of expression is 29.
What is substitution method?To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expression is,
⇒ 5w - x
And, w = 7 , x = 6
Since, The expression is,
⇒ 5w - x
Substitute the value of w and x, we get;
⇒ 5×7 - 6
⇒ 35 - 6
⇒ 29

a. 3y+(-2x)
b.-2+3y
c.2x-(-3y)
d.-3y-2x
Answer:
Hey there!!
Your required answer is option C.
The reason is;
In option A when you simplify the signs, you will get it as 3y-2x.In option B it's totally not matching. In option C, when you simplify the signs, you will get as 2x + 3y {as( - )× (- )= (+)}.Option D is not matching.Therefore, the possible answer is option D.

The probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The customers are on payment plan B = 23 customers
The customers on plan B text = 13 customers
The probability that a randomly selected customer who is on plan B uses the phone most often to text

A dripping tap loses 10mL of water every 45 seconds. How much water
will be lost in 6 hours?
Answer:
4800 ml
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask :)
Answer:
4.8 L
Step-by-step explanation:
6 hours = 6*60*60 seconds = 21600 seconds
10 mL - 45 seconds
x mL - 21600 seconds
x = (21600*10)/45=4800 mL
4800 mL = 4.8 L
The domain of the function f(x)=25/10x-20 is all rea numbers x excpet
Step-by-step explanation:

Find the median of the following data.
46, 24,87, 64, 39, 50, 37, 48
Answer:
47
Step-by-step explanation:
46, 24,87, 64, 39, 50, 37, 48
First put the numbers in order from smallest to largest
24, 37, 39,46, 48,50,64,87
Then we notice that there are 8 numbers. The median is the middle
24, 37, 39,46 , 48,50,64,87
The middle is between 46 and 48
Take the average of these numbers
(46+48)/2 = 94/2 = 47
The median is 47
Answer:
49
Step-by-step explanation:
Fairly simple, line up the numbers in order from lowest to highest. Then find the middle two terms. Since we have 8 terms, we take the two in the center, 50 and 48 and add them together, then divide by two to get your median.

Ms. Anderson made a New year's resolution to go on a diet and exercise more. On January 1st , she weighed 160 pounds. Two months later, she had dropped to 136 pounds. What was the percent of decrease in her weight?
Answer: 15%
Step-by-step explanation:
From the question, we are informed that Mrs Anderson weighed 160 pounds earlier and two months later, she had dropped to 136 pounds. To. Calculate the percent of decrease in her weight goes thus:
We've to find her decrease in weight first. This will be:
= 160 pounds - 136 pounds
= 24 pounds
Percentage decrease will now be:
= Change in weight/Original weight × 100
= 24/160 × 100
= 0.15 × 100
= 15%
The percent of decrease in her weight is 15%.

The error in this congruence statement is that we don't know if these are actually congruent.
Saying that the triangles "look the same" simply isn't enough. We do know that all three angles are the same, but the AAA (Angle Angle Angle) postulate only works for similar triangles.
Additionally, even if they were congruent, it would still be triangle ABC ≅ triangle FED, not triangle DEF.

If a=0 and b≠0, where will the graph of the complex number a+bi always lie?
Answer:
On the horizontal axis
Step-by-step explanation:
The complex number is represented by the complex plane or z-plane which is the representation geometrically of the real (number) axis and the imaginary (number) axis
When plotting complex numbers, the real part of the complex number is always plotted on the horizontal axis while the imaginary part is plotted on the vertical axis
The complex plane concept facilitates the description of complex numbers geometrically.

Liz is using the distributive property to evaluate the expression 27 (36) by using friendlier numbers. Her work is shown below. Liz's Work 27(36) Step 1 27 (3 + 12) Step 2 27 (3) + 27 (12) Step 3 81 + 324 Step 4 405
Answer:
Step 1 should have been 27(6 + 30).
Step-by-step explanation:
Given that:
The evaluation of the expression 27(36) by using the distributive property as portrayed by Liz is as follows:
27 (36)
Step 1 = 27 (3+ 12)
Step 2 = 27(3) + 27(12)
step 3 = 81 + 324
Step 4 = 405
What was the first error that Liz made?
From the above first step, we will see that :
27(3+12) was given, which is wrong.
the right step that is supposed to be there is:
27(6 + 30).
so the calculation will be:
Step 1 = 27(6+30)
Step 2 = 27(6) + 27(30)
Step 3 = 162 + 810
Step 4 = 972
Studio fee:$8 per hour
Vase:$10
Answer:
x = hours spent8x+10 = 464.5 hoursStep-by-step explanation:
We are asked for the number of hours spent at the studio, so it is reasonable to let the variable x stand for the number of hours.
The total cost is ...
vase cost + hourly cost = total cost
where hourly cost = (# of hours)(cost per hour)
10 + 8x = 46
8x = 36 . . . . . . subtract 10
x = 4.5 . . . . . . . divide by 8
4.5 hours were spent at the studio.
