7 0

Answer:

problem e. : x = 30.48

problem f. : x = 328.1

Step-by-step explanation:

first off, i looked at the ratio of the numbers that did not include x. for example, the denominator on the right side of problem e. is 12x the number on the left side. so, i just multiplied the right numerator by 12. i did the exact same thing for problem f. , just opposite.

Lin has 4 pinecones and some acorns.
frozen [14]

Answer:

Lin has 11 acorns ⇒ answer D

He subtract 4 from 7 instead of add 4 to 7

Step-by-step explanation:

- Lin has 4 pinecones and some acorns

- She has 7 fewer pinecones than acorns

- The meaning of 7 fewer pinecones than acorns is the number of the

   pinecones is less than the number of acorns by 7

∵ She has 4 pinecones

∵ She has 7 fewer pinecones than acorns

- The number of pine cones is less than the number of acorns by 7

∴ 4 = number of acorns - 7

- Add 7 to both sides

∴ 11 = number of acorns

*<em> Lin has 11 acorns</em>

- Tom choose answer A which is 3

- He made a mistake in the equation

- He put  ⇒ number of the acorns = 7 - 4 not 7 + 4

∴ number of acorns = 3

* <em>He subtract 4 from 7 instead of add 4 to 7</em>

2 triangles
Base 40, to find the height(dotted perpendicular line segment)
a^2 + b^2 = c^2. ... 20^2+ b^2 = 29^2 … 400+ b^2 = 841
- 400. -400
b^2 = 441 … b=21 this is height
1/2(40)(21) = 420 + 420

3 rectangles
Two are 70x29 = 2030 +2030
One is 70x40 = 2800

Add all 5 numbers:
420
420
2030
2030
+ 2800
7700
