Answer:
x = 18 y = 10
Step-by-step explanation:
let the first number be x
let the second number be y
x = y + 8..... equation 1
2x + y = 46.... equation 2
x is the larger number
y is the smaller number.
Rearrange the equation and add equation 1 to equation 2.
x - y = 8
+ 2x + y = 46
-------------------
3x + 0 = 54
3x = 54
divide both sides by 3
x = 54/3
x = 18
Substitute x = 18 into equation 1
x = y + 8
18 = y + 8
collect like terms
y = 18-8
y = 10
The two numbers are 18 and 10
From the question, One number is 8 more than another
Let the first number be x and the second number be y
∴ x = y + 8 ------ (1)
From the second statement, the sum of the smaller number and twice the larger number is 46
That is,
y + 2x = 46 ----- (2)
Now, we will solve the two equations simultaneously
From equation (1)
We have x = y + 8
Substitute this into equation (2)
y + 2x = 46
y + 2(y+8) = 46
Then, clear the bracket
y + 2y + 16 = 46
3y + 16 = 46
Collect like terms
3y = 46 - 16
3y = 30
∴ y = 30 ÷ 3
y = 10
Substitute the value of y into equation (1)
x = y + 8
x = 10 + 8
x = 18
∴ x = 18 and y = 10
Hence, the two numbers are 18 and 10

1. Annie bought 3 apples for Php 51.00. How much would 5 apples cost?
2. In a table ternis match, Adonis scores 2 points for every 3 that Lexus makes. What is Adonis final score if Lexus score is 217?
pls help me.. i dont know what this is.. answer this if u know it pls..
Answer:
[tex]5 \ apples = 85.00[/tex]
[tex]Adonis = 144.67[/tex]
Step-by-step explanation:
Solving (a):
[tex]3\ apples = 51.00[/tex]
Required
The cost of 5
Divide through by 3, to get the cost of 1
[tex]1\ apple = 17.00[/tex]
Multiply through by 5, to get the cost of 5
[tex]5 * 1\ apple = 17.00*5[/tex]
[tex]5 \ apples = 85.00[/tex]
Solving (b):
[tex]Adonis : Lexus = 2 : 3[/tex]
[tex]Lexus= 217[/tex]
Required
Find Adonis' final score
Substitute 217 for Lexus
[tex]Adonis : 217 = 2 : 3[/tex]
Express as fraction
[tex]\frac{Adonis}{217} = \frac{2}{3}[/tex]
[tex]Adonis = \frac{2}{3} * 217[/tex]
[tex]Adonis = \frac{2 * 217}{3}[/tex]
[tex]Adonis = \frac{434}{3}[/tex]
[tex]Adonis = 144.67[/tex]

The distance around a meteor crater is 9,799 ft. Find the diameter of the crater. Use 22 7 for π.
Answer:
3118.7ft
Step-by-step explanation:
Given data
Circumference= 9,799 ft
We want to find the diameter, but we need to get the radius
C= 2πr
9,799=2*22/7*r
9,799=2*3.142*r
9,799=6.284r
r=9,799/6.284
r= 1559.35
Hence the diameter is =1559.35*2
Diameter=3118.7ft

2. The useful life of a radial tire is normally distributed with a mean of 80,000 miles and a
standard deviation of 5000 miles. A small tire company produces 10,000 tires a month.
a What is the probability that if you buy a radial tire at random, it will last between
70,000 and 85,000 miles? (1 point)
b. About how many tires from a month's production will last between 75,000 and
85,000 miles? (2 points)
Answer:
1) 10000. When asked to pick a set of four decimal digits, then the total number of combinations possible are 10⁴. More generically speaking, if asked to pick a random set of n digits expressed in base b, then the total number of combinations available is bⁿ.
2a) 95%. According to the "Empirical Rule" 95% of data in a normal distribution falls within two standard deviations of the average.
2b) 68%. Again, using the Empirical Rule, we know that 68% fall within one standard deviation of the average.

What is a simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.
Simplification usually involves making the expression simple and easy to use later.
We have been given an expression;
T= 3x + 4y
when T= 38 and x = 6
38 = 3(6) + 4y
4y = 38 - 18
4y = 20
y = 5
