Answer:
Ben has 38 years older and jerry is 9 years old
work out the value of x
will give brainliest
Answer:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35

Answer:
250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

Jim's science class is making slime from cornstarch and glue. Jim is helping pass out materials. He gives each student 80 grams of cornstarch from a 2-kilogram bucket. If Jim's class has a total of 21 students, how many grams of cornstarch will he have left?
The total amount of corn starch left is 320 grams.
How to find the grams of corn starch left?He gives each student 80 grams of corn starch from a 2-kilogram bucket.
Each students collected 80 grams of corn starch.
Therefore,
1 student = 80 grams of corn starch
His class has a total of 21 students.
Therefore,
total mass of corn starch distributed = 21 × 80
total mass of corn starch distributed = 1680 grams
The corn starch from the bucket = 2 kg
1kg = 1000 g
2kg = 2000g
Hence,
The corn starch from the bucket = 2000 grams
Finally,
amount in grams of corn starch left = 2000 - 1680
amount in grams of corn starch left = 320 grams.

what is the numerical sum of the degree measures of ∠dea and ∠aeb?what are the numerical measures of the angles?x
The value of angles x, ∠DEA, and ∠AEB are 14.5, 39.5, and 140.5 degrees respectively.
What is an angle?An angle in Euclidean geometry is composed of two rays that share a common terminal and are known as the angle's sides and vertices, respectively. In the plane where they are positioned, two rays can create angles. When two planes overlap, angles are also created. These are the so-called dihedral angles. The angle formed by the rays that are perpendicular to the two intersecting curves at the point of junction is another property of intersecting curves. The length of an angle or rotation can also be described using the word angle.
Calculations:
Supplementary angles are angles that sum up to 180degrees.
We can see that:
m<DEA + m<AEB = 180
x+25+9x+10 = 180
10x + 35 = 180
10x = 180 - 35
10x = 145
x = 145/10
x = 14.5
Get ∠DEA
∠DEA = x + 25
∠DEA = 14.5 +25
∠DEA = 39.5 degrees
Get ∠AEB:
∠AEB = 9x+10
∠AEB = 9(14.5) + 10
∠AEB = 130.5 + 10
∠AEB = 140.5 degrees

30 fair ride tickets for $10 how much does one ticket cost
Answer:
$3
Step-by-step explanation:
The equation we can create for this respective problem is "10x = 30" where the 10 represents the dollars and the 30 represents the tickets. We can start off by dividing each side by 10 since the coefficient is accompanied by a variable, therefore, the inverse would be division. 30/10 equals 3, thus making the answer $3 per ticket.
Hope this helps! :D
Answer:
One ticket costs 0.333...
Hope this helps
Step-by-step explanation:
10 / 30 = 0.33333...
For example,
If it was 10 tickets for 30$, one ticket would cost 3$. But it is the opposite, it's 30 tickets for 10$.
30 / 10 = 3

Answer:
y = -1.50x + -3
---------------------------------------------
Step 1: Calculating Slope (m).
m = y2-y1/x2-x1
m = 3-0/-4--2
m = 3/-2
m = -1.50
Now putting value of m in equation (i)
y = -1.50x + b
Step 2: Calculating Y-intercept (b).
Lets choose the first point, (-2,0) for calculating y-intercept:
y = mx + b
0 = -1.50(-2) + b
0 = 3 + b
-3 = b
b = -3
Now putting value of b in equation
y = -1.50x + -3
