Write the inequality that matches the situation. The sum of twice a number and 5 is at most 15.
Answer:
See Below
Step-by-step explanation:
Ok, so you got:
The sum of twice a number and 5 is at most 15
Sum means we are going to add two things together, soo . .
___+___
Is at most means we are going to have:
___+___≤ ___
Twice a number and 5= 2x(a variable) + 5
(I'm going to use a as my variable, use whichever you like or are given)
2a + 5 ≤ __
Which will result in being greater than or equal to 15
So, your final equation would be:
2a + 5 ≤ 15

Evaluate f(x)=x+6 when x=−2,0, and 5.
f(−2)=
f(0)=
f(5)=
thank you
Answer:
f(-2) = 4
f(0) = 6
f(5) = 11
Step-by-step explanation:
You just need to plug in the different values of x into the equation
f(x)=x+6
When x = -2, then f(-2) = -2 + 6 = 4
When x = 0, then f(0) = 0 + 6 = 6
When x = 5, then f(5) = 5 + 6 = 11
f(5) = 11 , f(0) = 6 , f(-2) = 4
Given expression:
f(x) = x + 6
Find:
f(−2), f(0), f(5)
Computation:
f(x) = x + 6
When x = -2
f(-2) = -2 + 6
f(-2) = 4
When x = 0
f(0) = 0 + 6
f(0) = 6
When x = 5
f(5) = 5 + 6
f(5) = 11

Fitness For cardiovascular exercise, you do a combination of walking and running
for 60 minutes. During the 60 minutes, you end up running twice as much as
walking. Let x represent the number of minutes you ran and y represent the
number of minutes you walked. How many minutes did you run and how many
did you walk?
Answer:
You walked for 20 minutes and ran for 40 minutes
Step-by-step explanation:
System of Equations
Let x = the number of minutes you ran
y = the number of minutes you walked
Walking and running takes a total of 60 minutes, thus:
[tex]x+y=60\qquad\qquad [1][/tex]
Running time is twice as much as walking time, thus:
[tex]x=2y\qquad\qquad [2][/tex]
Solve the system by substitution. Taking x from [2] and substitute in [1]:
2y+y=60
Simplifying:
3y=60
Solving:
y=60/3=20
Calculate x from [2]:
x=2*20=40
You walked for 20 minutes and ran for 40 minutes
The grades on a history midterm at Gardner Bullis are roughly symmetric with μ = 69 μ=69mu, equals, 69 and σ = 3.5 σ=3.5sigma, equals, 3, point, 5. Ishaan scored 65 6565 on the exam. Find the z-score for Ishaan's exam grade. Round to two decimal places.
Answer:
-1.14
Step-by-step explanation:
The given information in statement is
mean=μ=69
standard deviation=σ=3.5
Let X be the Ishaan's exam score
X=65
The Z score can be computed as
[tex]z=\frac{x-mean}{standard deviation}[/tex]
[tex]z=\frac{65-69}{3.5}[/tex]
z=-1.1429
z=-1.14 (rounded to two decimal places).
Thus, the computed z-score for Ishaan's exam grade is -1.14.

Are these two triangles congruent why or why not!!!!!!!!!???????? WORTH 24 POINTS AND I WILL GIVE YOU BRAINIEST!!!!!!1111
Answer:
not congruent
Step-by-step explanation:
These two triangles are not congruent because for two shapes to be congruent to each other, both needs to have same shape and size and clearly, we can see in this figure that both triangles although are the same shape, are different sizes so therefore these two triangles are not congruent. For example, the height of triangle ADE is 4 whereas the height of triangle CBA is 2.

Answer:
It will take 3 days for their bird feeders to contain the same amount of bird seed
Step-by-step explanation:
Let the number of days it will take their bird feeder to contain the amount of bird seed be x
For Edith, the amount of birdseeds that will be left after x days will be;
4 1/2 - 3/4(x)
= 9/2 - 3x/4
For June, the amount of birdseeds that will remain after x days will be;
3 - 1/4(x)
= 3 - x/4
Since after x days, the amount of birdseeds will be equal;
Mathematically;
9/2 - 3x/4 = 3 - x/4
Let’s work with decimals to make things easier;
