The ratio of the number of cars Ed has to the number of cars Pete has was 5:2 at first. After Ed gave 30 cars to Pete, they had an equal amount of cars each. How many cars did they have altogether?
Answer:
5x=5(20)=20 for Ed
2x=2(20)=40 for pete
together they had 140 cars
Step-by-step explanation:
5:2 is the ratio
5x-30=2x+30 tat when Ed gave Pete 30 cars
solve for x
5x-2x=30+30
3x=60
x=20
substitute for x: 5x=5(20)=20 for ED
2x=2(20)=40 for pete

Identify the slope and intercept of the following linear equation. y=3/7x-5
Answer:
slope = m = 3/7
y-intercept = b = -5
Step-by-step explanation:
y = mx + b is the slope-intercept form of the equation of a line
where m = slope, and b = y-intercept.
slope = m = 3/7
y-intercept = b = -5

find the values of x and y
Answer:
x = 85 Degrees
y = 85 Degrees
Step-by-step explanation:
20 Degrees + 90 Degrees -->
90 and 20 are given => 110 Degrees
e triangle angles sum = 180 Degrees
180 - 110 = 70 Degrees
=> Vertical angles so 25 + x + 70 = 180
x = 85
x + (z) = 180 e sum of half 360
85 + z = 180
z = 95 Degrees
--> z + (y) = 180 e same as above (sum of interior angles)
95 + y = 180
y = 85

Which of the following steps were applied to ABCD to obtain A’B’C’D’ ?

Step-by-step explanation: they went 4 left and 3 up
Please help need to know the answer to this supposedly is 9 + (9x36) 333 but I don’t get it
Answer:
459
Step-by-step explanation:
First line:
clock showing 9 o'clock + clock showing 9 o'clock + clock showing 3 o'clock = 9 + 9 + 3 = 21
Second line:
The calculators look exactly the same.
3 * calculators = 30
1 calculator = 10
Third line:
1 bulb + 1 bulb - 1 bulb = 15
Since 1 bulb - 1 bulb = 0, we have 1 bulb + 0 = 15, or
1 bulb = 15
Last line:
Clock showing 9 o'clock = 9
Calculator = 10
3 bulbs = 3 * 15 = 45
Total = 9 + 10 * 45 = 9 + 450 = 459
Determine whether the two triangles can be proven congruent using the AAS congruence method. If they can, select the congruence statement. answers: A) ΔABC ≅ ΔEDC B) ΔCBA ≅ ΔCED C) The triangles aren't congruent using AAS. D) ΔCAB ≅ ΔEDC
Answer:
The A) ΔABC ≅ ΔEDC
Step-by-step explanation:
The AAS congruence method requires 2 angles and their un-included side to be congruent. ∠A ≅ ∠E due to the markings, ∠C ≅ ∠C because they are vertical angles, and AB ≅ ED due to the markings. 2 angles and their un-included side are congruent.
As for the congruence statement, A is the correct answer because ∠A ≅ ∠E, ∠B ≅ ∠D, and ∠C ≅ ∠C. The order of the naming of the triangles aligns to the angle's congruence.
Answer:
A) triangle ABC is congruent to triangle EDC
Step-by-step explanation:
The AAS method of proving congruence of triangles uses two angles and a non-included side of the triangle. If two angles and the non-included side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
Let's see what we have in this problem:
<ACB and <ECD are congruent since they are vertical angles.
<A and <E are congruent by given.
Sides AB and ED are non-included sides and are congruent.
Since we have two angles and a non-included side of a triangle and the corresponding parts of another triangle, the triangles are congruent by AAS.
Now we need the statement of congruence.
Angles ACB and ECD are corresponding angles, so the letter C must appear in both triangles in the same position.
Angles A and E are corresponding angles, so the letters A and E must appear in both triangles the same position.
We already have CA and CE. The last angles left are corresponding angles B and D, so we get triangle CAB and triangle CED. Since a triangle may be named using any order of the vertices, we can rename the triangles ABC and EDC and maintain the same corresponding vertices.
Answer: A) triangle ABC is congruent to triangle EDC

The quadratic equation is not factorized completely. The given factors are prime factors. Option A is correct.
What is prime factorization ?A mathematical quantity is factorized when it is expressed as multiples of smaller units of closely related quantities.
Factorization is the breakdown of an integer into smaller numbers that, when multiplied together, yield the original, considered number. Factors of those regarded as integers are those who make up an integer.
When all those factors are prime numbers, this is known as prime factorization. In other words, prime factorization expresses an integer in terms of prime multiples.
Given equation;
⇒3x²-x+5
The above quadratic equation is not factorized completely. The given factors are prime factors.

THANKS SO MUCH FOR YOUR HELP!!!
Answer:
1) 34 + 0i
2) 9/17 + (2/12)i
3) z = -i
Step-by-step explanation:
Part 1:(5 + 3i)(5 - 3i) = 25 - 15i + 15i - 9i²
25 - 15i + 15i - 9i² = 25 - 9i²
25 - 9i² = 25 - 9√(-1)²
25 - 9√(-1)² = 25 - 9(-1)
25 - 9(-1) = 25 + 9
25 + 9 = 34
