Answer:
7. M = (-1.5,7)
8. (8,4)
9. m<QRS=46°
Step-by-step explanation:
7. Use the midpoint formula which is (x1+x2/2 , y1+y2/2)
So (-1-2/2 , 9+5/2)
(-3/2 , 14/2)
So M = (-1.5,7)
8. This is one simple if you understand.
Since (-6,6) is the starting end point and (1,5) is the mid point then (8,4) has to be the other end point. -6 to 1 is +7. 1 to 8 is +7. 6 to 5 is -1. 5 to 4 is -1.
9. 3x-8+2x+6=98
5x-2=98
5x=100
x=20
So plug in x for QRS
2(20)+6
40+6
46

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Answers
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked
Which expression can be used to convert 488 miles to yards
Answers
Answer:
488 Miles (mi)
=
858879.99997 Yards (yd)
Step-by-step explanation:
mile is a most popular measurement unit of length, equal to most commonly 5,280 feet (1,760 yards, or about 1,609 meters). The mile of 5,280 feet is called land mile or the statute mile to distinguish it from the nautical mile (1,852 meters, about 6,076.1 feet). Use of the mile as a unit of measurement is now largely confined to the United Kingdom, the United States, and Canada.
Yards : A yard (symbol: yd) is a basic unit of length
We have that The expression for converting 488 miles to yards will be
488miles*1760yard
From the question we are told that
Convert 488 miles to yards
Generally the expression for the conversion is is mathematically given as
Where
1mile=1760yards
Therefore
The expression for converting 488 miles to yards will be
488miles*1760yard
In conclusion
The expression for converting 488 miles to yards will be
488miles*1760yard

Answers
the hcf of 90 and x is 18. the lcm of 90 and x is 540. find the value of x.
Answers
The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
Hence, the value of x is 108.

What x,y, and z?
Answers
Answer:
x=151/64 y=9/8 z=-51/32
Step-by-step explanation:
2x+2y+5z- (2x-y+z)=-1-2
3y+4z=-3
2x+2y+5z- (2x+4y-3z)=-1-14
-2y+8z=-15
We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)
3y+4z=-3 (2)
-2y+8z=-15 (-3)
6y+8z=-6
6y-24z=45
(6y+8z)- (6y-24z)= -6-45
32z=-51
z=-51/32
3y-204/32=-3
3y= -96/32+204/32
3y=108/32
y=36/32=9/8
2x+2*9/8+5*(-51/32)=-1
