Answer:

201.5x-y=-6

Step-by-step explanation:

−6x−2y=−1618x+6y=48

Collect like terms

-6x+1618x-2y-6y=-48

1612x-8y=-48

Divide through by 8

1612x/8-8y/8=-48/8

201.5x-y=-6

Laura shades 60 squares on her hundredths grid And Billy shades 50 squares on his hundredths grid. Write the decimal number that
Andre45 [30]

Answer:

Laura = 0.60

Billy = 0.50

0.60 > 0.50

Step-by-step explanation:

Given

Laura = 60\ shades

Billy = 50\ shades

Required

Represent using decimal number and compare

From the question, we understand that there are 100th grids;

So:

Laura = \frac{60}{100}

Laura = 0.60

Billy = \frac{50}{100}

Billy = 0.50

Comparing both decimals;

Since 0.60 is greater than 0.50, we have:

0.60 > 0.50

The Truth Table Represents Statement P,Q,R
Darya [45]

Recall that a ⇒ b ≡ ¬a ∨ b.

• r ⇒ (p ∧ q) ≡ ¬r ∨ (p ∧ q)

In row C, q is false so p ∧ q false, and r is true so ¬r is false.

¬r ∨ (p ∧ q) ≡ false ∨ false ≡ false

• r ⇒ (p ∨ q) ≡ ¬r ∨ (p ∨ q) = p ∨ q ∨ ¬r

In each of rows A, C, and E, at least one of p or q is true, so

p ∨ q ∨ ¬r = true

• (q ∧ r) ⇒ p ≡ ¬(q ∧ r) ∨ p ≡ (¬q ∨ ¬ r) ∨ p = p ∨ ¬q ∨ ¬r

In row E, p is false and both q and r are true, so ¬q and ¬r are both false.

false ∨ false ∨ false = false

• (q ∨ r) ⇒ p ≡ ¬(q ∨ r) ∨ p ≡ (¬q ∧ ¬r) ∨ p

In row E, p is false and both q and r are true, so both ¬q and ¬r are false.

(¬q ∧ ¬r) ∨ p ≡ (false ∧ false) ∨ false ≡ false ∨ false ≡ false

Find m/FEG<br><br> A.20<br> B.40<br> C.60<br> D.120
noname [10]
The inside angles of the triangle add to equal 180 and so does m/FEG with unknown triangle angle.

x+2x = x+40
2x = 40
x = 20

mFEG
= 20 + 40
= 60

What should the following equation be multiplied by to eliminate the decimals?6.74x-1.026=0.138.
Evgen [1.6K]

Answer:

b.1000

Step-by-step explanation:

6.74x-1.026=0.138

The smallest decimal goes to the thousandths place, so we need to multiply by 1000

.138

. tenths  hundredths  thousandths

Another way to look at it

.138 = 138/1000  so multiply by 1000 to get rid of the decimal

1.026 is to the same place value so we could pick either one to determine what to multiply by
