2a + 2c = 5a - 5b
recopilar términos ligeros.
toma 2a en el otro lado
2c = 5a -2a-5b
2c = 3a - 5b
divide 2c's 2 en ambos lados
y
c = (3a - 5b) / 2

Please help me with this sheet asap!!!!b
Step-by-step explanation:
1)
SA= 2 (Length x Breadth + breadth x height + Length x height)
SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2
2)
2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2
3)
2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2
4)
SA=
[tex]A=2πrh+2π {r}^{2}
[tex]A=2πrh+2π {r}^{2} [/tex]
= 2π 6*5+2π6*6= 188.495+226.194
SA= 414.689 cm^2
5)
2π7*4+2π*4*4=
SA=276.46 cm^2
6)
2π6*4+2π*4*4=
SA= 251.33 cm^2
7)
(3*4)/2=6
(3*4)/2=6
(3*8)=24
4*8=32
8*5=40
SA =6+6+24+32+40=108 cm^2
8)
(6*8)/2=24
(6*8)/2=24
6*12=72
8*12=96
10*12=120
SA= 24+24+72+96+120= 336 cm^2
9)
(5*12)/2=30
(5*12)/2=30
5*8=40
12*8=96
13*8=104
SA= 30+30+40+96+104= 300 cm^2

Step-by-step explanation:
The difference between half of a certain number and seven is the same as with adding two to that number...Find the number
Answer:
x = - 18
Step-by-step explanation:
Let certain number = x
The difference between half of a certain number and seven
x/2 - 7
is the same as
=
with adding two to that number
x + 2
Find the number
x/2 - 7 = x + 2
x - x/2 = - 7 - 2
( 2x - x ) / 2 = -9
2x - x = -18
x = - 18
What is the value of the expression below when a = -2, b = 3, C = -5
[a– 2ac + 56]
Answer:
34
Step-by-step explanation:
plug the coefficients in the equation, so
-2-2(-2)(-5)+56
Distribute the -2(-2)(-5), so it equals -20
so the equation is -2-20+56
add -20+56, so -2+36
-2+36=34
34 is your answer

1). m∠QPS = m∠TPV 1). Given
2). m∠QPS = m∠1 + m∠3 2). Angle addition postulate
m∠TPV = m∠2 + m∠4
3). m∠1 + m∠3 = m∠2 + m∠4 3). Given
4). m∠1 = m∠2 4). Given
5). m∠1 + m∠3 = m∠2 + m∠4 5). Subtraction property

ILL MARK U BRAINLIEST HELP!!!
Answer: x= 14
Step-by-step explanation: look at transversal ED. Angle E and angle D are alternate interior angles of this transversal. Alternate interior angles are equal. Now we need to find angle measure of D to solve. The triangle angle sum theorem states that all interior angles of a triangle sum to 180 degrees. 50+ 48 + D =180.
Measure of angle D is 82. Now that we have the two alternate interior angles, we set them equal to each other to solve.
6x-2= 82. Add 2 to both sides. 6x = 84. Divide both sides by 6. X =14

2x+5y=3
3x-2y=14
Answer:
x=−5/2 y+ 3/2
Step-by-step explanation:
Let's solve for x.
2x+5y=3
Step 1: Add -5y to both sides.
2x+5y+−5y=3+−5y
2x=−5y+3
Step 2: Divide both sides by 2.
2x/2
=
−5y+3
2x=

tan 30 = perpendicular / base = x/ 7
1/√3 = x/7
X= 7/√3
2.
cos 30 = 7/y
√3/2 = 7/y
y = 7×2/ √3
y= 14/√3
