Answer:
9/20
Step-by-step explanation:
first you have to make 1 1/4 an improper fraction so since the denominator is 4 you add 4 to the numerator which is 1 so your fraction would be 5/4.
Second you make the denominators the same so you have to multiply them together. but since your multiplying the denominators you have to multiply the numerator as well. so for 5/4 you would multiply both the numerator and denominator by 10 so your fraction will now be 50/40. now you multiply 8/10 by 4 so your new fraction is now 32/40
Third you subtract. you only have to subtract the numerators so 50-32 is 18 so your answer is 18/40
Last you need to simplify the highest number you can divide both of them by is 2 so now you divide 18 by 2 which makes 9 then you divide 40 by 2 which is 20 so your answer is 9/20

Which statements verify that the solution set to |x + 3| < 5 is –8 < x < 2? Check all that apply. Substituting a value into the inequality from the solution set, such as –2, will create a true statement. Substituting a value into the inequality from the solution set, such as 1, will create a false statement. Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. Substituting any value into the inequality will create a true statement.
Answer:
First and fourth statements are correct
Step-by-step explanation:
The function is [tex]|x+3|<5[/tex] where the domain is [tex]-8<x<2[/tex]
[tex]|-2+3|=1<5[/tex]
The first statement is correct.
[tex]|1+3|=4<5[/tex]
Substituting a value into the inequality from the solution set, such as 1, will create a false statement. This is wrong as it creates a true statement.
[tex]|4+3|=7\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. This is wrong as a value which is not from the solution set will create a false statement.
[tex]|6+3|=9\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. This is correct.
[tex]|10+3|=13\nless 5[/tex]
Substituting any value into the inequality will create a true statement. This is wrong as the value of x must be in the solution set.
Answer:
1.) Substituting a value into the inequality from the solution set, such as –2, will create a true statement.
4.) Substituting a value into the inequality not from the solution set, such as 6, will create a false statement.

Find the probability P(z < 0.37) using the standard normal distribution.
Answer:
0.6443
Step-by-step explanation:
Given the that:
P(Z < 0.37) ; using a standard normal distribution :
The probability can be obtained using several methods :
Using a standard normal distribution table ;
P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table
Hence,
P(Z < 0.37) = 0.6443
In triangle ABC, the measure of angle B is 18° more than twice the measure of angle A. The measure of angle C is 42° more than that of angle A. Find the angle measures. A: 30°, 78°, 42° B: 30°, 78°, 72° C: 33°, 84°, 63° D: 26°, 70°, 84°
Answer:
B: 30°, 78°, 72
Step-by-step explanation:
Given a [tex]\triangle ABC[/tex].
Let [tex]\angle A = x^\circ[/tex]
As per question statement, [tex]\angle B[/tex] is 18° more than twice of [tex]\angle A[/tex].
i.e
[tex]\angle B =(2x+18)^\circ[/tex]
[tex]\angle C[/tex] is 42° more than that of [tex]\angle A[/tex]
[tex]\angle C = (x+42)^\circ[/tex]
To find:
The angle measures of the triangle = ?
Solution:
We can use the angle sum property of a triangle here to find the three angles of the triangle.
As per angle sum property, the sum of all the three internal angles is equal to [tex]180^\circ[/tex].
[tex]\angle A + \angle B + \angle C= 180^\circ\\\Rightarrow x+2x+18+x+42=180^\circ\\\Rightarrow 4x+60=180\\\Rightarrow 4x=120\\\Rightarrow x= 30^\circ[/tex]
i.e. [tex]\angle A = 30^\circ[/tex]
[tex]\angle B = 2\times 30 + 18 = 78^\circ[/tex]
[tex]\angle C = 30+42 = 72^\circ[/tex]
Therefore, the correct answer is:
B: 30°, 78°, 72

A side of the triangle below has been extended to form an exterior angle of 156°. Find
the value of x
Answer:
x=24
Step-by-step explanation:
again 180-156=24
super easy remember exterior +interior angles add up to 180
Brainliest please
First angle = 105
Second angle = x
Third angle = 156 - 105
= 51
_________________________________________
Three angles of the triangle:
[tex]105[/tex]
[tex]x[/tex]
[tex]51[/tex]
___________________________________________
Angle sum of triangle = 180°
[tex]105 + 51 + x = 180[/tex]
[tex]156 + x = 180[/tex]
[tex]x = 180 - 156[/tex]
[tex]x = 24[/tex]
Enter a value for x that makes the equation 7x - 2(x + 1) + 18 = 8x - 11 true.
Answer:
9
Step-by-step explanation:
The given equation is true for x=-5/3.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 7x-2(x+1)+18 = 8x-11.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The solution for the equation 7x-2(x+1)+18 = 8x-11 is as follows
7x-2x-2+18 = 8x-11
⇒ 5x-16=8x-11
⇒ 8x-5x=-16+11
⇒ 3x=-5
⇒ x=-5/3
Verification:
Substitute x=-5/3 in the given equation and verify
That is, 5(-5/3)-16=8(-5/3)-11
⇒ -25/3 -16=-40/3 -11
⇒ (-25-48)/3 = (-40-33)/3
⇒ -73/3 =-73/3
LHS = RHS
Therefore, the given equation is true for x=-5/3.

Answer: Lunch:$16 Coffee: $4 Julie had $12 left.
Step-by-step explanation:
Answer:
1. Lunch ($16)
2. Coffee ($4)
3. how much money did she have left?
she had ($12) left
Step-by-step explanation:
1. To get the amount of money she used on lunch you have to look at the word problem it says "she spent 1/2 of her money on lunch" her total is $32 dollars and 1/2 is .5 as a decimal and 50% as a percentage so 50% of 32 is (16) so she spent $16 dollars on lunch alone.
2. To find how much money she used on Coffee you need to read the context of the problem its asking for "how much did she use of the money that is left from her lunch" so she has $16 dollars she used from lunch so now it wants you to find 1/4 of $16 dollars or 25% of 16 and 25% of 16 is (4)
so she spent 4 dollars of what was left so the answer is 4.
3. To find how much is left add up 16 and 4 and you get 20 then subtract it by the original number which is 32 so it should look like this 32 - 20 = 12
so the money she has left is $12 dollars.

OW> 36
Ow< 36
OW> 5
O w<5
Answer:
The width should be more than 5 m. So it can be 6,7 ...
Step-by-step explanation:
The length of a flower garden is = 9 m
The width of a flower garden is = w
The area of a flower garden > 45 sq. m
The area of a flower garden = l * b
l * b > 45
9 * b > 45

Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.
Answer:
x=y-44 and x+y=410
Step-by-step explanation:
So, you want to use the equations x=y-44 and x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.
