Answer:
6
Step-by-step explanation:
The difference of two numbers is 16. The greater number is 5 less than 4 times the smaller
number. Find the two numbers.
Answer:
x= 23
y=7
Step-by-step explanation:
x-y=16
4y-5=x
4y-5-y=16
3y-5=16 add 5 to both sides
3y=21 divide by 3 on both sides
y=7
x-7=16 substitute back in
x=23 added 7 to both sides
so x=23 and y=7
23-7=16
Find the measure of the exterior angle.
Answer:
120 degrees
Step-by-step explanation:
Because the triangle is a right triangle, it can be either a 45,45,90 triangle or a 30,60,90 triangle. I tested this problem with each scenerio, and I believe that it is a 30, 60, 90 triangle, with the top angle being 30 degrees, thus, making x=30. For the exterior angle, we'd multiply 4 by 30 to get 120 degrees.
I checked my answer by adding 120 to 60 (that's the degrees of the right hand corner of the triangle), which added to 180 degrees (aka a flat line), which verifies my answer.
I hope this helps! :)
help pleaseee i’ll put you as brainliest
Answer:
Step-by-step explanation:
If a boat has the speed = 15 miles per hour
Let the speed of the river = v miles per hour
If the boat is moving down stream, that means boat is traveling with the stream of the river.
So the speed of the boat downstream = (15 + v) miles per hour
Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.
write the point-slope equation of the line that passes through(3,5) and (7,1)
Answer: y - 1 = –(x –7)
or y –5 = –1(x –3)
The attachment shows the graph of these equations (identical)
Step-by-step explanation:
The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."
Subtract the first coordinate from the second coordinate.
Given coordinate points: (3,5) and (7,1) substitute values:
m= 1 –5 / 7 –3 becomes m= –4/4 so the slope, m = –4/4
That is –1 The "1" is "understood," so only the negative sign represents the slope in the equation
To write the equation: Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.
y - b = m(x - a) Using the second coordinate: (7,1)
y - 1 = –(x –7)
or using the first coordinate:
y –5 = –(x –3)
Find equation of the line shown
Answer:
y = x + 6
Step-by-step explanation:
y = mx + b
Since (0,6) is your y-intercept (or just positive 6), you have your b part of the equation solved.
The line goes up at a continuous rate of up 1, over 1, so they cancel each other out, making the m part of your equation 1.
So, you have y = 1x + 6 and you change it to just y = x + 6 (since x itself automatically has a 1 before it, when it's by itself).
Hope this helps!
Find the slope of the line that passes through (73, 73) and (7, -10).
Answer:
M= 83/66
Step-by-step explanation:
The formula to solve the slope is y2-y1/x2-x1 so ,
-10-73= -83
7-73= -66
-83/-66= 83/66

Carlos has $50 in his saving account. he deposits $100 on his birthday. Every month after his birthday, he deposits $25. which equation can be used to calculate the number of months it will take him to have $500?
Answer:
im not sure sorry..
Step-by-step explanation:
Answer:
so don't know the equation but it's 15 months. a year and 3 months.
Step-by-step explanation:
so first able, he already has 150 in his saving account. he adds 25$ every month after hai bday. a year has 12 months in which one of them is his birthday. so the rest 11 months he adds 25$. 25×11=275 then 150+275=425 so he needs 75 more dollars to have 500$ 25+25+25=75 so there fore we have 3 more months. so that means that a year and three months. sorry if you didn't understand I'm bad at explaining

Tom is building a new barn for all of his farm equipment.
He spend $35,000 in buying raw materials and $40,000 in labor and machinery to build the barn.
This total amount came out to be 20% less than what he had budgeted for the barn.
What was the amount he had budgeted for the barn?
Answer: $
Answer:
Build the barn : $35,000 + $40,000 = $75,000
Budgeted for the barn : $75,000 x 80% = $60,000

x + y = 10
y = ?
solution: (7, y)
Answer:
y=3
Step-by-step explanation:
Given: x+y=10
solution is (7,y)
put x=7 in x+y=10
⇒7+y=10
⇒y=10-7
⇒y=3
Hence, the value of y is 7.
Can someone please give me this answer.
Answer:32 inches
Step-by-step explanation:
Using the pythagorean theorem
40²= 24²+ b²
simplify
1600 = 576 + b²
subtract 576 from both sides
1024 = b²
square root both sides
32= b

Alex has 3,330 toothpicks . He wants to use them all to make a floor mat with 18 equal rows . How many toothpicks should Alex use for each row ?
Answer:
Step-by-step explanation:
for this problem we have to
3330/18=185 toothpicks for each row
Answer:
185

Divide 3330 by 18.
3330 is the number of tooth pics he has, so divide by how many rows he needs, 18.
Find VX.
A. 3.0
B. 2.6
C. 6.1
D. 4.6
Answer:
B
Step-by-step explanation:
You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using
Cosθ = Adjacent/hypotenuse.
cos49 = adjacent/4
1.32 = adjacent/4
2.62 = adjacent
VX = 2.6
Remember!
SOH
Sinθ = opposite/hypotenuse
CAH
Cosθ = adjacent/hypotenuse
TOA
Tanθ = opposite/adjacent
6 x 10^9 divide 3x10^4 = ____x10^?
Answer:
2 × 10⁵
Step-by-step explanation:
The following data were obtained from the question:
6×10⁹/ 3×10⁴ =?
The above expression can be simplified as follow:
6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴
Recall:
Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ
Therefore,
6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴
6×10⁹ ÷ 3×10⁴ = 2 × 10⁵
Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵

Answer the following questions using metric conversions.
13. One pack of Strawberry Poptarts has a mass of 104 g. What is the mass of 6 packs of Poptarts? How many kg is 6 packs of Poptarts? Explain your answer.
14. Will a tablecloth that is 155 cm long cover a table that is 1.6 m long? Explain.
15. Alex rode 2 kilometers on his bike. His sister rode 3000 meters on her bike. Who rode
the farthest and how much farther did they ride? (Answer in meters)
Answer:
Ok, here is the answers! brainliest pleaseee :D
Step-by-step explanation:
13. - 0.624 kg. (Explanation: 104 grams per one pack of pop-tarts. 104 g x 6 packs of pop-tarts equal 624 grams in total. 624 grams to kilograms is 0.624 kg.)
14. - No. The tablecloth is 155 cm long. It needs to cover a table that is 1.6 meters long. 155 cm to meters is 1.55 meters. The tablecloth is 0.05 to short to cover the table. 1.6 meters - 1.55 meters = 0.005.
15 - Alex's sister rode the farthest. She rode 1,000 meters farther than Alex. 2 kilometers in meters is 2,000 meters. His sister rode 1,000 meters more than that, 3,000.
