If x = 3 and y = 5, work out the value of 4x-2y and 2x² + 3y²
Answer:
4 × 3 - 2 × 5 = 12 - 10 = 2
2x² + 3y² = 2 × 9 + 3 × 25 = 18 + 75 = 93
George had $127 in his checking account on Thursday. He got paid on Friday and deposited $130.00 into his checking account. Then on Saturday, he wrote two checks: one for $167.00 and one for $42.00. What is his checking account balance after writing the checks
Answer:
The balance on George's checking account is $48.

The smaller moon of Mars, Deimos, has a diameter of 7.5 miles. The larger moon, Phobos, has a diameter that is 1 3 4 times greater. What is the diameter of Phobos?
Answer: 13.125 miles.
Step-by-step explanation:
Given : The smaller moon of Mars, Deimos, has a diameter of 7.5 miles.
The larger moon, Phobos, has a diameter that is [tex]1\dfrac34[/tex] times greater.
Diameter of Phobos = [tex]1\dfrac34\times\text{(Diameter of Deimos )}[/tex]
[tex]=\dfrac{7}{4}\times7.5 \ \ \ [1\dfrac34 =\dfrac{7}{4}]\\\\=13.125\text{ miles}[/tex]
Hence, the diameter of Phobos = 13.125 miles.

You guys are life savers but does anyone know the answers to these questions? I’m so confused rn
Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be [tex]\frac{3}{-1}[/tex] , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.

A charm bracelet costs $65, plus $25 for each charm, write an equation in standard form that represents the total cost y of a bracelet that has x charms please help!
Answer: , y = 65+25x
Step-by-step explanation:
Let x = Number of charms
Given : Fixed cost of bracelet = $65
On addition , cost per charm = $25
Total cost of bracelet = Fixed charge + (Charge per charm) x (number of charm)
If y= total cost.
Then, y = 65+25x , which is the required equation.

The sum of two numbers is 100, The difference between the two numbers is 95
workout the two numbers
Answer:
Let the numbers be x and y
x+y=100
x-y=95
taking x-y=95
x=95+y
x+y=100
95 + y +y = 100
2y=100-95
y=5/2
y=2.5
x=95+y
x=95+2.5
x= 97.5
Hope it helps...............
The two numbers are 97.5 and 2.5.
What is Addition and Subtraction?Subtraction is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Let x and y be the two numbers.
The sum is 100 and the difference is 95.
x + y = 100 ⇒ x = 100 - y
x - y = 95
Substituting x = 100 - y in the second equation,
100 - y - y = 95
100 - 2y = 95
2y = 100 - 95
2y = 5
y = 5/2 = 2.5
x = 100 - y = 100 - 2.5 = 97.5
Hence the numbers are 97.5 and 2.5.

Find the 13th term in the following arithmetic sequence
2, 10, 18, 26, ...
Answer:
Find the 13th term in the following arithmetic sequence
2, 10, 18, 26 ...192 is the 13th term
Answer:
a(13) = 98
Step-by-step explanation:
a(n) = a1 + (n-1) d
a1 would be the original term, 2
since you are looking for the 13th term a(n) and n is 13
a(13) = 2 + (13-1) d
d would be the difference between each term, 8
a(13) = 2 + (13-1) 8
Now solve
a(13) = 2 + 12 * 8
a(13) = 2 + 96
a(13) = 98

Hours it takes Elena and Jada to meet: (2 points)
Answer:
The hours it takes Elena to meet Jada = 4 hours
Step-by-step explanation:
The distance between Elena and Jada = 32 miles
The speed with which Elena runs = 6 miles per hour
The speed with which Jada walks = 2 miles per hour
Let t, represent the time it takes until Elena and Jada meets, we have;
Distance = Speed × Time
The total distance covered by both Elena and Jada before they meet = The distance between them = 32 miles
The distance covered by Elena before meeting Jada = Elena's speed × The time that elapsed for them to meet
∴ The distance covered by Elena before meeting Jada = 6 mph × t
The distance covered by Jada before meeting Elena = Jada's speed × The time that elapsed for them to meet
∴ The distance covered by Jada before meeting Elena = 2 mph × t
The total distance covered by both Elena and Jada before they meet = The distance covered by Elena before meeting Jada + The distance covered by Jada before meeting Elena = 32 miles
∴ The total distance covered by both Elena and Jada before they meet = 6 mph × t + 2 mph × t = 32 miles
t × (6 mph + 2 mph) = 32 miles
t × 8 mph = t × 8 miles/hour = 32 miles
t = 32 miles/(8 miles/hour) = 4 hours
The time it takes until Elena and Jada meets = t = 4 hours
